Type two statements using nextInt() to print two random integers between (and including) 0 and 9. End with a newline. Ex: 7 Note: For this activity, using one statement may yield different output (due to the interpreter calling randGen.nextInt() in a different order). Use two statements for this activity.

double x = 5 / 20; System.out.println(x); What answer do you get? The answer is imprecise! Write a Java program that precisely calculates the decimal value of a fraction, and prints the answer to the screen. The value displayed must be accurate. Sample Run: Please enter the numerator: 5 Please enter the denominator: 20 The decimal value is: 0.25

Hi, I am struggling a bit with this problem. (This is in Java by the way.) Provided code: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); String userText; // Add more variables as needed    userText = scnr.nextLine(); // Gets entire line, including spaces. /* Type your code here. */ }}
Fix the code so it runs. Take note of what errors are generated by the compiler. What do these errors mean? How do they help you find and fix the errors? import java.util.Scanner; public class Main {public static void main(String[] args) {  int numOfBooks = 130;char bookStoreAns;   do {System.out.println("Are you at the book store? (y/n)");bookStoreAns = scnr.next().charAt(0);boolean atBookStore; if (bookStoreAns == 'y') {atBookStore = true;} else if (bookStoreAns == 'n') {atBookStore = false;}} while (bookStoreAns != 'y' && bookStoreAns != 'n'); if (atBookStore) {numOfBooks += 4;} System.out.println("I have " + numOfBooks + " books."); }} Can anyone fix this code in Java?
Question 1: Write a complete Java program - with your own code writing - that contains: 1. A main method 2. Another method that returns a value 3. An array in the main method 4. A loop: for, while, or do-while 5. A selection: if-else or switch Question 2: Test your program. Ensure that it runs correctly (syntax error free).
Please explain the questions below. //8. Experiment with the below code. When would you use this data type? // In Java "or" is represented by || and "and" is represented as && //boolean x = 0; //boolean x = true; //x = !x; //x = x || false; //System.out.println(x); //9. Explain what's going on here. //char x = 'A'; //char x = 65; //char x = 'A'; x++; //char x = 12; //System.out.println("x = " + x);
Write in-line comments that are necessary. Don't write a comment for what is obvious from the code. There are 2 different programs. (Subject is JAVA PROGRAMMING) First Program: // Main.java import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter the Carrier: "); String carrier = input.nextLine(); System.out.print("Enter the Type: "); String type = input.nextLine(); System.out.print("Enter the Speed: "); double speed = Double.parseDouble(input.nextLine()); System.out.print("Enter the Memory: "); double memory = Double.parseDouble(input.nextLine()); System.out.print("Enter the Number Of Apps: "); int numApps = Integer.parseInt(input.nextLine()); CellPhone p1 = new CellPhone(carrier, type, speed, memory, numApps); System.out.println("\nCarrier = " + p1.getCarrier()); System.out.println("Type of phone = " + p1.getType()); System.out.println("Speed of phone = " + p1.getSpeed() + " Ghz");…
