Using this to access a field
In case a field is shadowed by method or constructor parameter, the field can be accessed using this keyword.
public class Example {
public int val;
public Example(int val) {
this.val = val;
}
public static void main(String[] args) {
Example obj = new Example(10);
System.out.println(obj.val);
}
}10
Using this to call another constructor of same class
public class Example {
public int val;
public Example() {
this(100);
}
public Example(int val) {
this.val = val;
}
public static void main(String[] args) {
Example obj = new Example();
System.out.println(obj.val);
}
}100
