If that delimeter is always just a single character have a look at the two argument split( ... ) method. You still have to insert those delimeters in the resulting array yourself though. Pay special attention when that delimeter occurs at the end of the original String. The two argument split( ... ) method can tell you if that is so.

kind regards,

Simply I think you can count the number of element in return array and as Jos says pay attention on delimiters at the end of the original string.

Can u check please ?? am i on the right direction ??

String string = "John-is-very-angry";
String []arr;
String s;
int j;
int x;
int i =0;
int j = 0;
while(i < string.length()){
if((string.indexOf('-', i ) != -1)){
x = string.indexOf('-', i );
s = string.substring(i, x);
i = x;
System.out.println(s);
i++;}

}

You define variable j twice in wrong way.

int j;
int x;
int i =0;
int j = 0;

It should be,

int j = 0;
int x;
int i =0;

Did you run your code? If so what happen?

while (i < string.length()) {

In the above line of code you compare the length of the string, that's the number of characters. And see how many time you increase the variable i. Only if you find - sign int the string you've. How many, 4. So what happen, after that the i is not increase. So that,

while (i < string.length()) {

never evaluate as false. So that there is no way to exist the loop. You comes into a infinite loop.
