Generics Problem

Hello!
>

I tried the following code(from an example)

>

public class Test {
private Integer i = new Integer(4);
private String s = new String("FFFF");
HashMap<Integer, String> hash = new HashMap<Integer, String>();
hash.put(i , s);
}

It becouse you should do thi within method body call:
public class Test {
private Integer i = new Integer(4);
private String s = new String("FFFF");
HashMap<Integer, String> hash = new HashMap<Integer, String>();
public void foo() {
hash.put(i , s);
}
}

or

public class Test {
private Integer i = new Integer(4);
private String s = new String("FFFF");
HashMap<Integer, String> hash = new HashMap<Integer, String>();
{
hash.put(i , s);
}
}

Thanks!

oops!....
thanks :)

By the way you shouldn't be using implementation classes as types. :) At least, not for collections classes. This is considered better form:

 hash = new HashMap();]]>

Also...just curious... but why, when using the jdk 1.5 beta, do we still need the jsr based collection.jar and gjc-rt.jar.

Shouldn't these be in the 1.5 JDK?

You don't need collect.jar and gjc-rt.jar when using jdk 1.5. Just "-source 1.5" compiler flag

You don't need collect.jar and gjc-rt.jar when using jdk 1.5. Just
"-source 1.5" compiler flag

I get an error message sating cannot locate collect.jar in my Idea lib folder. Where should I put this compiler flag?

You need to turn off the "use generics-enabled compiler" checkbox. It shouldn't be looking for collect.jar.

Thanks

That got it!

We'll fix this in Pallada - it will honor the check only for JDK 1.4 versions.

Hello Eugene,

We'll fix this in Pallada - it will honor the check only for JDK 1.4
versions.

So, you have two ways to use Generics -- use JDK 1.4 plus configuring the "Setup JSR014 Implementatin" wizard with downloadable Generics goodies -- AND -- simply using JDK 1.5 Beta (turning off 'use generics compiler' under compiler settings)?

...and the second way you have to pass -source 1.5 to jdk1.5 javac.

P.S. Sorry for being wrong Eugene=)
