CODE -

//java code
import java.lang.Math;
public class pT{

    public static float percentTrue(boolean[] a){

        float ct, pt;
        ct = 0;
        pt = 0;
        if(a.length == 0){
            System.out.println("Array is empty");
        }
        else{
            for(int i = 0; i < a.length; i++){
                if(a[i] == true)ct = ct + 1;
            }
            pt = ct/a.length * 100;
        }
        return pt;
    }
     public static void main(String []args){
         boolean[] array = {true, false, true, false, false, false, true};
         System.out.print("The elements are ");
         for(int i = 0; i < array.length; i++){
             System.out.print(array[i] + " ");
         }
        System.out.println("\nThe percentage of elements having the value true is " + Math.round(percentTrue(array) * 10) / 10.0 + "%");
     }
}

JAVA PLEASE!! Write a value-returning method, isVowel, that returns the value true if a given character is a vowel, and otherwise returns false. Also write a program to test your method. 2) Write a program that prompts the user to input a sequence of characters and outputs the number of vowels. (Use the method isVowel written in Programming Exercise 1.)

In Java Write a method countOddInternalNodes that returns the number of internal nodes in a binary tree that contain odd numbers. You are essentially writing a method that will become part of the IntegerTree class. You may define private helper methods to solve this problem. Make your own trees in the main method of the code. I specifically kept vague the way the nodes are being added to the tree so you can practice building your own trees from scratch...

write the “largerComponents” method that takes in two integer arrays and returns true or false if the first array’s components are strictly greater than the second array’s components. The arrays must be the same size or else return false. Clarification Note: Components meaning each value at a specific index. For instance, if we had the arrays {5,2,7} and {1,3,1} then this method would return false as the value “2” is not greater than “3”. here is a provided code //Do...

1. Write a method called isPalindrome that accepts a string as a parameter and returns true if the string is a palindrome otherwise returns false. This method uses a stack and a Queue to test whether the given string parameter is a palindrome [ that is, whether the characters read the same both forward and backward. For example “race car”, and “Are we not drawn onward, to new era.” are Palindromes] They are palindrome sentences, not just a word. 2....
