Java String Exercises: Read a string and if a substring of length two appears at both its beginning and end, return a string without the substring at the beginning otherwise, return the original string unchanged

Java String: Exercise-64 with Solution

Write a Java program to read a string and if a substring of length two appears at both its beginning and end, return a string without the substring at the beginning otherwise, return the original string unchanged.

Sample Solution:

Java Code:

import java.util.*;
public class Main
{
public String withoutMacth(String str) 
{
  int len = str.length();
  if (len == 2)
    return "";
  if (len < 2)
    return str;
  else 
  {
    if (str.substring(0,2).equals(str.substring(len-2, len)))
      return str.substring(2,len);
      else return str;
  }
}

public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "educated";
	  
      System.out.println("The given strings is: "+str1);
      System.out.println("The new string is: "+m.withoutMacth(str1));
	  }
}

Sample Output:

The given strings is: educated
The new string is: ucated
