Question

Consider the given program and answer the questions given below:

class temp
      {
      int a;
      temp()
      {
      a=10
      }
      temp(int z)
      a=z;
      }
      void print()
      {
      System.out.println(a);
      }
      void main()
      {
      temp t = new temp();
      temp x = new temp(30);
      t.print();
      x.print();
      }
      }
  

1. What concept of OOPs is depicted in the above program with two constructors?
