Java: Printing out all the integers in args array

Question

How do I print out a set of integers from my args variable in Java?

I tried:

System.out.println("The numbers are " + args.length);

But all that does is print out the number of elements in the array.

I want it so that if there are 5 arguments passed: 1 2 3 4 5 the output should be:

1, 2, 3, 4, 5

Answer 1

Take a look if you like

  System.out.println("The numbers are "+Arrays.toString(args));

If not, you'll have to loop over the array and format it yourself.

Answer 2

But all that does is print out the numbers in the array not the numbers separately.

This seems to be somewhat unclear.

args.length gives the length of the array rather than its elements.

Use a for loop:

System.out.println("The numbers are ");

for(int i=0; i < args.length; i++)
    System.out.print(args[i] + " ");

Answer 3

Try:

for(String arg: args)
    System.out.print(arg + " ");
