Creating method to print array of integers

**kferd** · May 7th, 2014, 08:05 PM

I am trying to create a method that takes an array of integers and prints it out using System.out.print. I'm having trouble creating the right way to print it out since I cannot find a way to convert the int array to a string to print it out.

 
public static String printArray(int[] num){
 
	for (int i=0; i<num.length;i++){
		String msg = num[i];
	}
	return System.out.print(msg + " ");
	}

a way to convert the int array to a string

You can't get the contents of an array without accessing each of its elements one at a time.
The String class and the Integer class both have methods that will convert an int value to a String.
Take a look at the API doc to see what they are.

The compiler will automatically convert an int to a String if the code uses the + operator between a String and an int. For example: (""+123)
