The difference between this and super in java

This points to the current object, used to access its methods and properties, and is often used in constructors; super points to the parent class, used to call parent class methods or access its properties, and is often used to override parent class methods or access Properties that are not overridden.

The difference between this and super in Java

This and super are both keywords in Java , which are used to access methods and properties of a class.

this

• this keyword is used to refer to the current object.
• It allows you to access the methods and properties of the current object without explicitly specifying the object name.
• is often used in constructors to initialize object state.

super

• super keyword is used to refer to the parent class.
• It allows you to call the parent class's methods and access the parent class's properties.
• is often used to override parent class methods or access properties of the parent class that are not overridden by the subclass.

Main differences

Features	this	super
Purpose	Reference the current object	Reference the parent class
Scope	Current class	Parent class
Syntax	this.propertyName/methodName	super.propertyName/methodName
Initialization	Initialize the object state in the constructor	Access the constructor of the parent class
Override Method	cannot be used to override parent class methods	can be used to override parent class methods

Example

<code class="java">class Parent {
    public void printName() {
        System.out.println("Parent");
    }
}

class Child extends Parent {
    @Override
    public void printName() {
        System.out.println("Child");
    }

    public void callSuper() {
        super.printName(); // 调用父类的方法
    }
}</code>

Output:

<code>Child
Parent</code>
