Question

I have cmd like this one:

java Test -p 127.0.0.1:8080 -d D:\Desktop\temp.exe -o mingw -s 1024 -t 2000

I want to get the args with -p,-d or -s(exclude -p,-d,-s itself), and discard other args.

I tried hours but had no result,is there any one can help me?

I tried the arg[i] and arg[i+1] way,but if args like this:-p -d xxx, the user do not enter -p value, this solution will take no effect and cause problems.

Answer 1

If all your options are in same form -x value, then you can split your args array into groups in form of -d 127.0.0.1:8080, -d D:...

for(int i=0; i < args.length; i+=2){
    //group args
}

for each group in groups:
    if group[0].equals("-d"){
          //do something
    }
}

Or, just have a look at existing OptionParser libraries in Java. How to parse command line arguments in Java?
