Java program for making string to lowercase entirely if it is containing any uppercase letter in it.

Description:-

This java program converts the string into a string which will have only lowercase letters in it if that string had uppercase at the time of given it as an input.

Code:-

public class Solution {

    public String solve(String A) {

        char[] chArray = A.toCharArray();

        for(int i=0;i<chArray.length;i++){

            if(chArray[i]>='A' && chArray[i]<='Z'){

                chArray[i]= (char) (chArray[i]+32);

            }

        }  

        return String.valueOf(chArray);

    }

}
