i'm pretty new java , still have alot learn. i'm trying output data within variable text file, , i'm not sure why not work. me out?
if ("y".equals(output_to_file)) { system.out.print("you selected yes"); printstream out = null; try { out = new printstream(new fileoutputstream("filename.txt")); out.print(first_input); } { if (out != null) out.close(); } } else system.out.print("you selected no");
"(new fileoutputstream("filename.txt"))" underlined red, , says: unhandled exception: java.io.filenotfoundexception
thanks help!
anytime you're doing file operations, there possiblity filenotfoundexception
thrown. therefore, java wants tell in event 1 thrown. thus, need add catch
clause possible filenotfoundexception
. have try block, need add catch
clause before finally
clause:
try { out = new printstream(new fileoutputstream("filename.txt")); out.print(first_input); } catch(filenotfoundexception e) { //do in event fnfe thrown } { if (out != null) out.close(); } }
