Translate the following pseudocode for randomly permuting the characters in a string into a Java
Read a word.
Repeat word, length () times
Pick a random position i in the word, but not the last position.
Pick a random position j > i in the word.
Swap the letters at positions j and i.
Print the word.
To swap the letters, construct substrings as follows:
Then replace the string with
first + word.charAt(j) + middle + word.charAt(i) + last

- Write a program in java to check whether a string is a rotation of another. Take both string from user. In O(1)arrow_forwardUse for loops in Java Language Write the method catDog.* * Given a String str, return true if the words "cat" and "dog" appear the same* number of times in the string.* * Examples: catDog("catdog") returns true catDog("catcat") returns false* catDog("1cat1cadodog") returns true* * @param str the String to examine.* @return true if there are the same number of cats and dogs.arrow_forwardLanguage: Java Write a program that reads a sentence from the keyboard. Depending on the last character of the sentence, print the message identifying the sentence as declarative (ends with a period), interrogative (ends with a question mark), exclamatory (end with an exclamation point), or other. Hint: you can use charAt() method from the String class to extract the last character of the input line. The character of a String str is at str.length()-1 position. For taking a sentence as input use the nextLine() method from the Scanner class. You have to use if/else if selection. Sample input and output: Sample 1 Input: How are you? Output: Interrogative Sample 2 Input: I am good. Output: Declarative Sample 3 Input: That is amazing! Output: Exclamatory Sample 4 Input: Although, Output: Other Answer:arrow_forward
- Please &-. Write a Java program to check if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward, ignoring spaces, punctuation, and capitalization. For example, "racecar" and "Madam" are palindromes, while "hello" and "Java" are not. Your program should take a string as input and return true if it's a palindrome, and false otherwise. Ik.?arrow_forwardif strings are immutable, like in Java, we can assume that they have a static length True Falsearrow_forwardjava program Write code that accomplishes the following tasks. Consider two bags that can hold strings. One bag is named letters and contain seeral one-letter strings. The other bag is empty and is namedvowels. One at a time removed a string from letters. If the string contain a vowel place it into bag vowels, otherwise, discard the string. After you have checked all of the strings in letters, report the number of vowels and the number of times each voewl appears in the bag.arrow_forward
- Using Javascript and HTML: An interesting application of computers is drawing graphs and bar charts (sometimes called histograms). Write a script that reads five numbers between 1 and 30. For each number read, output HTML5 text that displays a line containing the same number of adjacent asterisks. For example, if your program reads the number 5, it should out HTML5 test that displays *****.arrow_forwardArtificial Intelligence- Java program Write code that accomplishes the following tasks.

Join the three initialized Strings string1, string2, and string3. Count the number of white spaces in the complete string. Use toUpperCase() and replaceAll("\\s", "") methods to convert string into Upper Case and remove all white Spaces from the string. Count the number of letters in the string. Find the first occurrence of S, U, I, T in the String and return indices of S, U, I, T. Strings are given below: String string1 = "Globalization and Information Technology continue to process at a dramatic pace" String string2 = "To answer the demand of a changing society Pakistan higher education system needs to shift its focus from individuals who simply absorb knowledge to those who are able to creatively utilize knowledge to excel in unfamiliar situations"; String string3 = "These creative individuals should be able to track…arrow_forward
- Write a code that generates a random lowercase letter. In java programming. Note: Not a string of letters just one letter is generated every time the program is run. meaning the output should not be something like this: a c t c -that's a random string, it should only be one random letter generated randomly.arrow_forward1) We will find out the character that gets repeated maximum times in a string. For example, in string "apple", 'p' repeats maximum times. Write a program in Java to find out the maximum repeated character in a string. solve in javaarrow_forwardWrite 3 ways in java to find the string length without using length method. I am asking without length method where you can use length keyword.please code this alsoarrow_forward
