Printing Variables in Java

Once variables are declared and initialized, you can print their values using the System.out.println() or System.out.print() methods.

Key Topics

1. Printing Variables

You can print variables directly by passing them to the print methods.

public class PrintVariables {
    public static void main(String[] args) {
        int age = 30;
        System.out.println(age); // Prints: 30
    }
}

2. String Concatenation

You can combine strings and variables using the + operator.

public class StringConcat {
    public static void main(String[] args) {
        String name = "Bob";
        int age = 25;
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
    }
}

Output:

Name: Bob
Age: 25

Key Takeaways

  • Use System.out.println() to print variables to the console.
  • Combine variables with strings using the + operator for concatenation.
