Answer:
import java.util.*;
public class Main{
 public static void main(String[] args) {
     Scanner input = new Scanner(System.in);
  int intgVal; double dblVal; char chrVal; String strVal;
  System.out.print("Enter integer: ");  
  intgVal = input.nextInt();
  System.out.print("Enter double: ");  
  dblVal = input.nextDouble();
  System.out.print("Enter character: ");  
  chrVal = input.next().charAt(0);
  input.nextLine();
  System.out.print("Enter string: ");  
  strVal = input.nextLine();
  System.out.println(intgVal+" "+dblVal+" "+chrVal+" "+strVal);
  System.out.println(strVal+" "+chrVal+" "+dblVal+" "+intgVal);
  int IntValue = (int) dblVal;
  System.out.print("Cast to an integer: "+IntValue);
 }
}
