    Default What is the problem with this following declaration in JDK 1.4?

    Hi,

    My application requires me to declare the following line..

    Hashtable<String, ArrayList> GraphMap = new Hashtable<String, ArrayList>();

    This line in not running if I run it in Jdk 1.4 (on a remote server)

    It is giving me the following errors:

    research% javac LBLGraphPrep.java

    LBLGraphPrep.java:45: not a statement
    Hashtable<String, ArrayList> GraphMap = new Hashtable<String, ArrayList>();
    ^
    LBLGraphPrep.java:45: ';' expected
    Hashtable<String, ArrayList> GraphMap = new Hashtable<String, ArrayList>();
    ^
    LBLGraphPrep.java:77: cannot resolve symbol
    symbol : variable GraphMap
    location: class LBLGraphPrep
    if (GraphMap.containsKey(tokens[1])) {
    ^
    .....

    However, it is running on higher versions (my laptop has NetBeans and higher version of JDK, it is running there fine). I need to run this on this server because my application is memory intensive, and my personal computer does not support that.

    Please help. What should I do?

    thanks in advance.

    -S

    Please do not post the same question in multiple sub-forums. Your duplicate post has been deleted.

    Java 1.4 doesn't support generics.

    Java 5 only added the support for Generics.
