Java String : Exercise-23 with Solution

Write a Java program to find whether a region in the current string matches a region in another string.

Java Code:

public class Exercise23 {
    
  public static void main(String[] args)
    {
       //String str1 = "Red Green Orange Yellow";
        //String str2 = "Yellow Orange Green Red";
        
        String str1 = "Shanghai Houston Colorado Alexandria";
        String str2 = "Alexandria Colorado Houston Shanghai";

        // Determine whether characters 0 through 7 in str1 
        // match characters 28 through 35 in str2.
        boolean match1 = str1.regionMatches(0, str2, 28, 8);

        // Determine whether characters 9 through 15 in str1 
        // match characters 9 through 15 in str2.
        boolean match2 = str1.regionMatches(9, str2, 9, 8);

        // Display the results of the regionMatches method calls.
        System.out.println("str1[0 - 7] == str2[28 - 35]? " + match1);
        System.out.println("str1[9 - 15] == str2[9 - 15]? " + match2);
    }
}

Output:

str1[0 - 7] == str2[28 - 35]? true                                      
str1[9 - 15] == str2[9 - 15]? false

    {
       //String str1 = "Red Green Orange Yellow";
        //String str2 = "Yellow Orange Green Red";
        
        String str1 = "Shanghai Houston Colorado Alexandria";
        String str2 = "Alexandria Colorado Houston Shanghai";

        // Determine whether characters 0 through 7 in str1 
        // match characters 28 through 35 in str2.
        boolean match1 = str1.regionMatches(0, str2, 28, 8);

        // Determine whether characters 9 through 15 in str1 
        // match characters 9 through 15 in str2.
        boolean match2 = str1.regionMatches(9, str2, 9, 8);

        // Display the results of the regionMatches method calls.
        System.out.println("str1[0 - 7] == str2[28 - 35]? " + match1);
        System.out.println("str1[9 - 15] == str2[9 - 15]? " + match2);
    }
}
