import java.util.Arrays;
import java.util.Scanner;
public class ObjectArrayToStringArray {
   public static void main(String args[]){
      Scanner sc = new Scanner(System.in);
      //Integer array to String
      System.out.println("Enter 5 integer values: ");
      int intArray[] = new int[5];
      for(int i=0; i<5; i++){
         intArray[i] = sc.nextInt();
      }
      System.out.println("Contents of the integer array: "+Arrays.toString(intArray));
      //float array to String
      System.out.println("Enter 5 float values: ");
      float floatArray[] = new float[5];
      for(int i=0; i<5; i++){
         floatArray[i] = sc.nextFloat();
      }
      System.out.println("Contents of the float array: "+Arrays.toString(floatArray));
      //double array to String
      System.out.println("Enter 5 double values: ");
      double doubleArray[] = new double[5];
      for(int i=0; i<5; i++){
         doubleArray[i] = sc.nextDouble();
      }
      System.out.println("Contents of the double array: "+Arrays.toString(doubleArray));
      //byte array to String
      System.out.println("Enter 5 byte values: ");
      byte byteArray[] = new byte[5];
      for(int i=0; i<5; i++){
         byteArray[i] = sc.nextByte();
      }
      System.out.println("Contents of the byte array: "+Arrays.toString(byteArray));
      //char array to String
      System.out.println("Enter 5 character values: ");
      char charArray[] = new char[5];
      for(int i=0; i<5; i++){
         charArray[i] = sc.next().toCharArray()[0];
      }
      System.out.println("Contents of the char array: "+Arrays.toString(charArray));
      //object array to String
      System.out.println("Enter 5 String values: ");
      Object objArray[] = new Object[5];
      for(int i=0; i<5; i++){
         objArray[i] = sc.next();
      }
      System.out.println("Contents of the object array: "+Arrays.toString(objArray));
   }
}
