Print Hello World Without using a Semicolon in Java

Every statement in Java must end with a semicolon as per the basics. However, unlike other languages, almost all statements in Java can be treated as expressions. However, there are a few scenarios when we can write a running program without semicolons. If we place the statement inside an if/for statement with a blank pair of parentheses, we don’t have to end it with a semicolon. Also, calling a function that returns void will not work here as void functions are not expressions.

Methods: 

1. Using if-else statements
2. Using append() method of StringBuilder class
3. Using equals method of String class 

Method 1: Using if statement

Java

// Java program to Print Hello World Without Semicolon
// Using if statement

// Main class
class GFG {

    // Main driver method
    public static void main(String args[])
    {

        // Using if statement to
        // print hello world
        if (System.out.printf("Hello World") == null) {
        }
    }
}

Output

Hello World

Method 2: Using append() method of StringBuilder class

Java

// Java Program to Print Hello World Without Semicolon
// Using append() method of String class

// Importing required classes
import java.util.*;

// Main class
class GFG {

    // Main driver method
    public static void main(String[] args)
    {

        // Using append() method to print statement
        if (System.out.append("Hello World") == null) {
        }
    }
}

Output

Hello World

Method 3: Using equals method of String class

Java

// Java Program to Print Hello World Without Semicolon
// Using equals() method of String class

// Importing required classes
import java.util.*;

// Main class
class GFG {

    // Main driver method
    public static void main(String args[])
    {
        // Using equals() method to print statement
        if (System.out.append("Hello World").equals(null)) {
        }
    }
}

Output

Hello World
