Question about the task

Overloading constructors

Java Core, Level 5, Lesson 12

Under discussion

I have no ideas now, Can someone give me a hand ? Thanks,

1. In the Solution class, create 4 constructors with different access modifiers.
2. In a separate file, create a SubSolution class and make it a child of the Solution class.
3. In the SubSolution class, use the Alt+Insert -> Constructors command to create constructors.
4. Correct the SubSolution constructors' access modifiers so that there are 3 constructors with different access modifiers (all except private).

Requirements:

The SubSolution class should have 3 different constructors.
The Solution class should have 4 different constructors.
The Solution class must define constructors with all possible access modifiers.
The SubSolution class must define constructors with all possible access modifiers except private.
The Solution class must be the parent of the SubSolution class.

package com.codegym.task.task15.task1523; /* Overloading constructors */ public class Solution { int number ; double d; char c; String s; public Solution(int i) { this.number = i; } protected Solution(double d) { this.d = d; } Solution(char c) { this.c=c; } private Solution(String s) { this.s=s; } public static void main(String[] args) { } }
