Java Output

Java Output: In Java, you can produce output using the System.out.print, System.out.println, and System.out.printf methods. Here are some examples to illustrate how each of these works:

Using System.out.print

The print method prints the text to the console without adding a new line at the end.

public class PrintExample {
    public static void main(String[] args) {
        System.out.print("Hello, ");
        System.out.print("world!");
    }
}

Output:

Hello, world!

Using System.out.println

The println method prints the text to the console and adds a new line at the end.

public class PrintlnExample {
    public static void main(String[] args) {
        System.out.println("Hello, world!");
        System.out.println("This is a new line.");
    }
}

Output:

Hello, world!
This is a new line.

Using System.out.printf

The printf method allows you to format strings using format specifiers. It’s useful for creating formatted output.

public class PrintfExample {
    public static void main(String[] args) {
        int age = 25;
        String name = "Alice";

        System.out.printf("Name: %s, Age: %d", name, age);
    }
}

Output:

Name: Alice, Age: 25

Summary

• System.out.print: Prints text without a newline.
• System.out.println: Prints text with a newline.
• System.out.printf: Prints formatted text using format specifiers.

By using these methods, you can control how output is displayed in your Java programs.
