Kuidas saab programmi praegust Instance objekti kuvada või vaadata?

In Java, to output the current object (instance) from within a class, you typically override the toString() method. This allows you to see information about the object when calling System.out.println(this).

Example:

public class MyClass {
    private int id;
    private String name;

    public MyClass(int id, String name) {
        this.id = id;
        this.name = name;
    }

    @Override
    public String toString() {
        return "MyClass{id=" + id + ", name='" + name + "'}";
    }

    public void printInstance() {
        System.out.println(this); // Will display information about the object
    }
}

// Usage:
MyClass obj = new MyClass(1, "Test");
obj.printInstance();

If you want to see the object during debugging, you can use your IDE's debugger, which will show all fields of the current instance.
