Question

Differentiate between the following statements:

abc p = new abc();
abc p = new abc(5,7,9); 

Answer 1

S.No.	abc p = new abc();	abc p = new abc(5,7,9);
1.	As illustrated below, the statement abc p=new abc() calls the default constructor.	The statement abc p=new abc(5,7,9) calls the parameterised constructor (seen below). The numbers 5, 7, and 9 are copied to formal parameters x, y, and z, which are used for setting the class's instance variables.
2.	abc() { }	abc(int x, int y, int z) { }
