WAP to accept a string and display length of string and string in lowercase

 

Approach :

We will be using 'length()' method to calculate length of String and 'toLowerCase()' method to convert lowercase string to lowercase. 

Take a input from the user using Scanner class and then use 'toLowerCase()' method to convert the string to lowercase. 

You can use 'toUpperCase()' to convert the String to UpperCase

Code :

import java.util.Scanner;

public class length {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter a String :-");
        String str = sc.nextLine();
        String LowStr = str.toLowerCase();
        System.out.println("Length of String : "+str.length());
        System.out.println("Original String : "+str);
        System.out.println("Lowercase : "+LowStr);
    }
}

Output :

Enter a String :-

ABHAY KUMAR

Length of String : 11

Original String : ABHAY KUMAR

Lowercase : abhay kumar

Convert String to uppercase
