Question
Write a sample Java code that run of the program should look something like output:
- use the .length(), .substring(), .indexof(), functions in your code.
- Note:
The important thing to note here is that the "4" in input.substring(0,4) is the index of the space character, and the "5" in input.substring(5) is that index plus 1. So we can get the first and last names using:
space = input.indexOf(' '); firstName = input.substring(0,space); // Everything before the space lastName = input.substring(space+1); // Everything after the spaceBy the way, this program will only work correctly if the user follows the instructions. If the user's input does not contain a space, then the value of input.indexOf(' ') will be -1, and the -1 will cause the program to crash when used in the substring function

- Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segmentarrow_forwardMake a Simple unit converter in Python that supports (length and time) and inputs the value and the initial unit measurement. Using the mentioned measurements (length and time). The user will pick either length or time. it then computes and shows the three types of conversion (Ex. 12 inches = (1) foot/feet, (30.48) centimeters, (304.8) millimeters). The unit conversion program allows the user to input a chosen conversion and repeats the program until the word “stop” is typed.arrow_forwardWrite a program that will read a line of text and output the number of words in the line and the number of occurrences of each letter. Define a word to be any string of letters that is delimited at each end by either whitespace, a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, and periods. When outputting the number of letters that occur in a line, be sure to count uppercase and lowercase versions of a letter as the same letter. Output the letters in alphabetical order and list only those letters that occur in the input line. For example, the input line I say Hi. should produce output similar to the following: 3 words 1 a 1 h 2 i 1 s 1 yarrow_forward
- IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n). The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.arrow_forwardWrite a program that reads integers userNum and divNum as input, and outputs userNum divided by divNum four times.Note: End with a newline.

So I need to prompt user to input a student ID, then the 1st course ID, then the grade, then the 2nd course ID- then grade, the the 3rd course ID then grade, then the 4th course ID then grade, then finally the 5th course ID then grade. Then it needs to go through the same thing 10 times (for a total of 10 students). It also says the user is asked to "Enter ID for student #s" where s is an integer from 1 through 10, indicating the student (and I don't really know how to do that but I tried as I googled java); AND "Enter course ID #n, where n is an integer from 1 through 5, indicating the course number. And last it needs to verify for grade entry that only the A, B, C, D, or F are entered.I started writing notes to try to keep track of where thing are…arrow_forward
- Write an improved version of the chaos . py program from Chapter 1 thatallows a user to input two initial values and the number of iterations, and then prints a nicely formatted table showing how the values changeover time. For example, if the starting values were . 25 and . 26 with 10iterations, the table might look like this: index 0.25 0.26----------------------------1 0 . 731250 0 . 7503602 0 . 766441 0 . 7305473 0 . 698135 0 . 7677074 0 . 821896 0 . 6954995 0 . 570894 0 . 8259426 0 . 955399 0 . 5606717 0 . 166187 0 . 9606448 0 . 540418 0 . 1474479 0 . 968629 0 . 49025510 0.118509 0 . 974630arrow_forwardHow to write a program in java that ask the user for an input word(use the String method toUpperCase to convert the word to all upper-case characters), then have the program keep looping, generating random strings until the random string matches the user word and keep track of how many loops were required to match. Each time through the loop, your program should output the user’s word, the random string, and the difference score. The difference score is the sum of the absolute value of the difference between each character in the random string and the user’s input string. For example, if the random string was “ABC” and the target string was “AAA”, then the difference score is 3 (abs(A-A) + abs(A-B) + abs(A-C) = 0 + 1 + 2 = 3). You can get at the characters of a string, using the String charAt and absolute value is the abs method of the java.lang.Math class. To generate random strings, in a loop, generate random characters to build up a random string the same length as the user word. To…arrow_forwardWrite using pythonarrow_forward
- Help writing a Java program (please provide photos it works so I'm not studying a nonworking program) Write a complete version of the Bresenham Midpoint algorithm to handle ALL slope values. Include appropriate tests for ‘special case’ conditions. Instead of “WritePixel” write to the screen the coordinates of the pixel that would be drawn. Your program must implement the algorithm given in class with modifications to handle the special cases. Different slope values: m = 0, m = 1, m = > 1, m = infinity (needs special test case) , m < 0 (swap x and y) The user should be able to enter coordinates and it should output the coordinates it takes to draw from the first point to the last pointarrow_forwardMake A Dice Simulator in Python. First, we import the library that allows us to choose random numbers. import random Now, we can generate a random number and save it in a variable, We will call it rolled Python library random has a function called randint (). The randint (min number, max number) requires 2 parameters (the lowest number and the highest number between we will pick our number randomly). In this case, our dice goes between 1-6. rolled = random.randint (1,6) If we want to show our selected number, we can use print (). Your code should look like this: import random rolled - random.randint(1,6) print(rolled) Nice, we already have our main engine working, now it's time to make it look more appealing. To do that we will add some improvements (we will use a new variable to store random generated numbers - rolled_num) import random rolled num - random.randint(1,6) print("You rolled: ", rolled num) If we run the code again, we should see a little message and the random number. Our…arrow_forwardI am trying to write a java code to see if the number entered by the user is a factor of the random number generated from the import java.util.Random. When I run it it keeps saying the number entered by the user is not a factor of the random number. Another thing is the output is suppose to look like this... The value <number entered by user> is a / not a factor of <random number> how would I fix what i have to look like that?arrow_forward
