Java String Exercises: Append two strings; remove characters from the beginning of longer string if the lengths of the string are different

Java String: Exercise-60 with Solution

Write a Java program to read two strings append them together and return the result. If the strings are different lengths, remove characters from the beginning of longer string and make them equal length.

Sample Solution:

Java Code:

import java.util.*;
public class Main
{
public String minCat(String st1, String st2) 
{
  if (st1.length() == st2.length())
    return st1+st2;
  if (st1.length() > st2.length())
  {
    int diff = st1.length() - st2.length();
    return st1.substring(diff, st1.length()) + st2;
  } else 
  {
    int diff = st2.length() - st1.length();
    return st1 + st2.substring(diff, st2.length());
  }
}
public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "Welcome";
	  String str2 =  "home";
	  
      System.out.println("The given strings is: "+str1+" and "+str2);
      System.out.println("The new string is: "+m.minCat(str1,str2));
	  }
}

Sample Output:

The given strings is: Welcome and home
The new string is: comehome
