    Default Creating method to print array of integers

    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)
    If you don't understand my answer, don't ignore it, ask a question.
