Question

I have a string:

strArray= "-------9---------------";

I want to find 9 from the string. The string may be like this:

strArray= "---4-5-5-7-9---------------";

Now I want to find out only the digits from the string. I need the values 9,4, or such things and ignore the ‘-‘ . I tried the following:

strArray= strignId.split("-");

but it gets error, since there are multiple ‘-‘ and I don’t get my output. So what function of java should be used?

My input and output should be as follows:

input="-------9---------------";
    output="9";
input="---4-5-5-7-9---------------";
    output="45579";

What should I do?

Answer 1

You don’t use split!

Split is to get the things BETWEEN the separator.

For this you want to eliminate the unwanted chars; ‘-‘

The solution is simple

out=in.replaceAll(“-“,””);
