How to call a method in Java?

To call a method in Java, do this: object.myMethod().

Here's how you do it:

public class Example {

  public void printHello() {
    System.out.println("Hello!");
  }

  public void print(String text) {
    System.out.println(text);
  }
}

Example example = new Example();

// 1) Call a method without parameters
// This will print: Hello!
example.printHello();

// 2) Call a method with a parameter
// This will print: Hello World!
example.print("Hello World!");

// 3) Call a static method
double twoSquared = Math.pow(2, 2);
System.out.println(twoSquared); // 4.0
