3.2 Output

As discussed previously in 1.2 First Program, we use System.out.println("Output message") to show output.

Difference between println() and print()

println() will print the message and automatically put the cursor in the next line.

However, print() will leave the cursor just after the output message.

print("This is a test message\n") and println("This is a test message") will produce the same output.

Printing values of variables

public class OutputTest {

    public static void main(String[] args) {
        int x = 42;
        System.out.println(x); // This prints 42 to the console. 
    }
}
