Java String Exercises: Check whether two strings of length 3 and 4 appear in same number of times in a given string

Java String: Exercise-81 with Solution

Write a Java program to check whether two strings of length 3 and 4 appear in same number of times in a given string.

Sample Solution:

Java Code:

import java.util.*;
public class Main
{
public boolean checkSameAppearance(String stng) 
{
  int l = stng.length();
  int red = 0;
  int blue = 0;
  for (int i = 0; i < l - 2; i++) 
  {
    String tmp = stng.substring(i, i+3);
    if (tmp.compareTo("red") == 0)
      red++; 
     }
  for (int i = 0; i < l - 3; i++) 
  {
    String tmp = stng.substring(i, i+4);
    if (tmp.compareTo("blue") == 0)
      blue++; 
  }
  
  if (red == blue)
    return true;
  else
    return false;
}

public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "redcapmanwithbluecar";
      System.out.println("The given string is: "+str1);
      System.out.println("The appearance of red and blue are same: "+m.checkSameAppearance(str1));
	  }
}

Sample Output:

The given string is: redcapmanwithbluecar
The appearance of red and blue are same: true
