Question

Computer Science. Java programming language. Data Structures.

1) List all the nonprimitive types of data structures.

2) Write a simple program for each of them (in Java)

Answer 1

List all the nonprimitive types of data structures.

Ans: nonprimitive data types do not store a value but they store a reference to that value. Nonprimitive types in Java is

1. Class
2. Interface
3. Array
4. String
5. Object

2) Write a simple program for each of them (in Java)

//interface is the nonprimitive type
interface abc
{
   int a=12;
   void dis();
}
//bank class is nonprimitive type
class bank implements abc
{
   public void dis()
   {
       System.out.println("welcome");
   }
}
public class nonrefernceDataTypes {

   public static void main(String[] args) {
       // TODO Auto-generated method stub
      
       //ob object is nonprimitive type
       bank ob=new bank();
       ob.dis();
      
       //String s and array arr is nonprimitive type
       String s="welcome";
       int arr[]=new int[10];
   }

}
