1. Introduction

In this blog post, we will be looking at how to check if a given string ends with a specified suffix in Java. This is a common operation that is useful in various scenarios, such as file extension validation and string manipulation.

2. Program Steps

1. Define the main method, which is the entry point of our program.

2. Initialize the string we wish to check and the suffix.

3. Utilize the endsWith method of the String class to determine if the string ends with the given suffix.

4. Print the result to the console.

3. Code Program

public class SuffixChecker {

    public static void main(String[] args) {
        // Step 2: Initialize the string we wish to check and the suffix
        String mainString = "JavaProgrammingLanguage";
        String suffix = "Language";

        // Step 3: Utilize the endsWith method to check if the string ends with the given suffix
        boolean endsWithSuffix = mainString.endsWith(suffix);

        // Step 4: Print the result
        System.out.println("Does the main string end with the specified suffix? " + endsWithSuffix);
    }
}

Output:

Does the main string end with the specified suffix? true

4. Step By Step Explanation

– Step 1: The main method serves as the entry point of our Java program.

– Step 2: We initialize mainString with the value "JavaProgrammingLanguage" and suffix with the value "Language".

– Step 3: We call the endsWith method on mainString with suffix as the argument, which returns a boolean indicating whether mainString ends with suffix.

– Step 4: The program then prints the result, showing whether the original string ends with the specified suffix.

This Java program effectively demonstrates how to use the endsWith method to verify whether a string concludes with a specific suffix, a technique applicable in numerous programming situations.
