There are several useful toString() and deepToString() methods in java.util.Arrays class.
String[] strings = { "foo", "bar", "waa" };
System.out.println(Arrays.toString(strings)); // [foo, bar, waa]
An alternative is to just loop over them yourself and print each item separately.

Using Apache Commons Lang:
org.apache.commons.lang.StringUtils.join(Arrays.asList(strings), ", ");
Using Spring Core:
org.springframework.util.StringUtils.collectionToDelimitedString(Arrays.asList(strings), ", ");

You can do it using for loop.
Here's example :
String[] colors = {"red","blue","black","green","yellow"};
for (String color : colors) {
System.out.println(color);
}

As quoted by Esko in above link is best answer:
In Java 5 Arrays.toString(arr) or Arrays.deepToString(arr) for arrays within arrays.
Note that Object[] version calls .toString() of each object in array. If my memory serves me correct, the output is even decorated in the exact way you're asking.
