What is the method called for invoking a Java structure?

In Java, there is no separate concept of structures. Instead, structures are represented through classes. Therefore, to use the functionality of structures, you can create a class instead.

In Java, ways to call a struct involves:

  1. Create a class to represent a data structure, with member variables and methods.
  2. Instantiate objects of a class, and access instance variables and methods through the objects.
  3. Constructors can be used to initialize the state of an object.
  4. It is possible to define methods in a class to manipulate the member variables of a data structure.

The sample code is as follows:

public class MyStruct {
    private int data1;
    private String data2;
    
    public MyStruct(int data1, String data2) {
        this.data1 = data1;
        this.data2 = data2;
    }
    
    public int getData1() {
        return this.data1;
    }
    
    public String getData2() {
        return this.data2;
    }
    
    public void setData1(int data1) {
        this.data1 = data1;
    }
    
    public void setData2(String data2) {
        this.data2 = data2;
    }
    
    public void printData() {
        System.out.println("Data1: " + this.data1);
        System.out.println("Data2: " + this.data2);
    }
}

public class Main {
    public static void main(String[] args) {
        MyStruct myStruct = new MyStruct(10, "Hello");
        
        System.out.println("Data1: " + myStruct.getData1());
        System.out.println("Data2: " + myStruct.getData2());
        
        myStruct.setData1(20);
        myStruct.setData2("World");
        
        myStruct.printData();
    }
}

In the example above, a MyStruct class is defined to represent a structure, which includes two member variables, data1 and data2, and provides corresponding methods to access and manipulate these member variables. In the Main class, a MyStruct object is instantiated and the appropriate methods are called to operate on and output the data.
