Find string and append text in java text file -

hi sorry bad things.

this text file

[testresult] testdate=5/16/2013 testtime=20:03:00 operator=jacob poulsen test_no=62495 axles_tested=2 [axle1result] fric_l=38 fric_r=51 p0_l=0 p0_r=0 fl=280 fr=300 

so find issue first find string ex:
second append text before [axle1result]
this

[testresult] testdate=5/16/2013 testtime=20:03:00 operator=jacob poulsen test_no=62495 axles_tested=2 [sometext] something=0 something=0 something=0 [axle1result] fric_l=38 fric_r=51 p0_l=0 p0_r=0 fl=280 fr=300 

what should do???

this should solve problem:

bufferedreader br= new bufferedreader(new filereader("yourfilename.txt")); string datarow=null; string temptext=""; while ( (datarow= br.readline()) datarow != null){     if(datarow.equalsignorecase("[axle1result]"){         temptext+="[sometext]";         temptext+=system.getproperty("line.separator");         temptext+="something=0";         temptext+=system.getproperty("line.separator");         temptext+="something=0";         temptext+=system.getproperty("line.separator");         temptext+="something=0";         temptext+=system.getproperty("line.separator");     }     temptext+=datarow;     temptext+=system.getproperty("line.separator"); }  filewriter writer = new filewriter("yourfilename.txt"); writer.append(temptext);     writer.flush(); writer.close();
