Java tostring method

Question

0.00/5 (No votes)

See more:

I expect Arrays.toString(char[] a) to return a String value similar to String.valueOf(char[] a), but it is converting whole array into a string.. For example:-

char[] a = {'a','b','c','d'}; 
System.out.println(Arrays.toString(a)); // returns  [a,b,c,d]

Why is it not returning abcd like String.valueOf()?

What I have tried:

Using Arrays.toString() method

If you look at the documentation: Arrays (Java Platform SE 7 )[^] it is very explicit: it is one os a set of toString overloads that provides a quick and easy way to print the contents of an array woth each element easily identifiable, hence separated by commas.
Pass an array of integers, and it gives you [1,2,3]. Pass an array of chars, and it gives you [a, b, c]
