Constructors in java
Method name same as Class Name
void Sample3 is a method not a Constructor
package com.scjp.test;
public class Sample3
{
void Sample3()
{
System.out.println("I am Constructor");
}
public static void main(String[] args)
{
Sample3 objSample3 = new Sample3();
}
}
OP:
Overloading Constructors
package com.scjp.test;
class Sample3
{
public static void main(String args[])
{
Vasko objVasko1 = new Vasko(54);
Vasko objVasko2 = new Vasko();
System.out.println(objVasko1.Size);
System.out.println(objVasko2.Size);
}
}
class Vasko
{
int Size;
Vasko()
{
}
Vasko(int s)
{
Size = s;
}
}
