There are two uses of this in Java:
1, representing the current class
public class dog{
private String name;
private float age;
Public SetName (String name) {
THIS.name = name;
}
}
This is the current dog class represented here. THIS.name can be understood as dog.name, just understanding, not equal.
2. Use in constructors
public class dog{
private String name;
private int age;
A constructor that has a parameter
Public Dog (String name) {
THIS.name = name;
}
Public Dog (String Name,int age) {

}
