  示例

  static方法意味着它可以在不创建类，不像的对象来访问public：

  public class MyClass {
    // Static method
    static void myStaticMethod() {
      System.out.println("Static methods can be called without creating objects");
    }
  
    // Public method
    public void myPublicMethod() {
      System.out.println("Public methods must be called by creating objects");
    }
  
    // Main method
    public static void main(String[ ] args) {
      myStaticMethod(); // Call the static method
      // myPublicMethod(); This would output an error
  
      MyClass myObj = new MyClass(); // Create an object of MyClass
      myObj.myPublicMethod(); // Call the public method
    }
  }
