  • Java - get index of key in HashMap?

    - by llm
    In java if I am looping over the keySet() of a HashMap, how do I (inside the loop), get the numerical index of that key? Basically, as I loop through the map, I want to be able to get 0,1,2...I figure this would be cleaner than declaring an int and incrementing with each iteration. Thanks.

  • Checking for a null int value from a Java ResultSet

    - by ian_scho_es
    In Java I'm trying to test for a null value, from a ResultSet, where the column is being cast to a primitive int type. int iVal; ResultSet rs = magicallyAppearingStmt.executeQuery(query); if (rs.next()) { if (rs.getObject("ID_PARENT") != null && !rs.wasNull()) { iVal = rs.getInt("ID_PARENT"); } } From the code fragment above, is there a better way to do this, and I assume that the second wasNull() test is redundant? Educate us, and Thanks

  • Wrapper class for HttpGet / Post in Java?

    - by Tim Green
    Hi, Sorry, I'm quite new to Java. I've stumbled across HttpGet and HttpPost which seem to be perfect for my needs, but a little long winded. I have written a rather bad wrapper class, but does anyone know of where to get a better one? Ideally, I'd be able to do String response = fetchContent("http://url/", postdata); where postdata is optional. Thanks!

  • Detect use of older Java libraries

    - by Tony Morris
    Is there a third party library to detect the use of a Java 1.5 library when compiling with a 1.5 compiler with -source 1.4 and -target 1.4? I could use a 1.4 rt.jar in the bootclasspath however I hope there is a better way. To be used, for example, to fail the compile/build if a newer library is used.
