Question

Write a "for loop" that displays a string in the reverse order (DO NOT use the reverse method) 3.

Answer 1

Following are the code in java to reverse any string without using reverse function.

import java.util.*; // import package

class Main // class

{

public static void main(String args[])  // main class in java

{

String s, r = "";  // string variable

Scanner out = new Scanner(System.in);  // scanner classes to take input

System.out.println("Enter a string to reverse");

s = out.nextLine();  // input string

int l1 = s.length();  // finding length of string

l1=l1-1;

for ( int i = l1 ; i >= 0 ; i-- )  // for loop to reverse any string

{

r = r + s.charAt(i);

}

System.out.println(" The Reverse String is: "+r);  // print reverse string

  }

}

Explanation:

firstly we input any string ,finding the length of that string then after that iterating over the loop by using for loop and last display that reverse string

output

Enter a string to reverse
