Merge 3 strings in Java

The program is designed to merge three strings ("Dog", "Cat", and "Mouse") into a single string, with each value separated by commas.

public class StringMerger {
    public static void main(String[] args) {
        String str1 = "Dog";
        String str2 = "Cat";
        String str3 = "Mouse";

        String mergedString = str1 + "," + str2 + "," + str3;
        System.out.println("Merged string: " + mergedString);
    }
}

Output:

Merged string: Dog,Cat,Mouse

1. Class Definition (StringMerger):
   • We define a class called StringMerger.
   • This class contains a main method, which serves as the entry point for our program.
2. String Variables (str1, str2, str3):
   • We declare three string variables: str1, str2, and str3.
   • Each variable holds a specific string value (“Dog,” “Cat,” and “Mouse”).
3. Concatenation:
   • Using the + operator, we concatenate these strings along with commas.
   • The result is stored in the mergedString variable.
4. Printing the Result:
   • Finally, we print the merged string to the console.
