Issues in getting the output when calling a python script from Java -

i've java program call python script. i've used exec method. please find code snippet below:

python program (which gather portion of text wikipedia), when run separately, gives me proper output. when called java, i'm not getting complete output python program.

i checked status of bufferedreader object using ready() method ( explained here, , code entered infinite loop.

i think others have faced similar problems-https://stackoverflow.com/a/20661352/3409074

can me?

      public string enhancedata(string name,string entity) {             string s = null;             stringbuffer output = new stringbuffer();             try{                 string command="python c://enhancer.py "+name+" "+entity;                 process p = runtime.getruntime().exec(command);                 bufferedreader stderror=new bufferedreader(new inputstreamreader(p.geterrorstream()));                 bufferedreader stdinput = new bufferedreader(new inputstreamreader(p.getinputstream()));                 while ((s = stdinput.readline()) != null) {                      system.out.println(s);                     output.append(s);                   } 

the while loop condition has read line double reading every time in loop.

while ((s = stdinput.readline()) != null) {     //s=stdinput.readline();  <- don't need     system.out.println(s);     output.append(s); }
