Cannot compile in 1.5

[Nischal Topno]

I just started with java 1.5 and I am not able to compile the following code:

import java.util.List;
import java.util.ArrayList;
import java.util.Iterator;
 
public class Test {
public static void main(String args[]) {
List<Integer> myIntList = new LinkedList<Integer>();
}
}

It throws the following error:

Test.java:7: '(' or '[' expected
                List<Integer> myIntList = new LinkedList<Integer>();

I have not installed the jdk 5 but copied the "j2sdk1.5.0" folder from another machine. I earlier thought it to be a path problem so i copied my source file in to j2sdk1.5.0\bin folder and tried compiling it, which gave me the same error.

Can any body help me the silliest mistake i am making.

I have not installed the jdk 5

Hmm. This might be the source of your problem. Run "java -version" to see which version you are really using.

I did thought that this might be an issue & so have changed the path and other variables to point to the folder where this jdk is copied. Following is the output:

C:\temp>javac Test.java
Test.java:7: '(' or '[' expected
                List<Integer> myIntList = new LinkedList<Integer>();
                                                        ^

C:\temp>java -version

Okay, "java" is 1.5, but what about "javac"? Run:

$javac -J-version

Or just "javac -version" -- new switch in Java 5!

Hi,

I am trying to compile the file in the bin folder itself, but still it does not compile.

D:\j2sdk1.5.0\bin>javac -version Test.java
javac 1.5.0-beta
Test.java:7: '(' or '[' expected
                List<Integer> myIntList = new LinkedList<Integer>();
                                                        ^

Install JDK 5 properly, that will solve your problem.
Just copying the jdk1.5.0 folder from another machine does not work.

Use Java5 with Eclipse as your editor. Eclipse gives you compliance options (1.3, 1.4, 5), so you can be aware of what version of Java you are coding to.

[Mark Spritzler]

Also, your version shows that it is a beta version of Java 1.5. So that is over a year old. Java 1.5 is in production for over a year.

I suggest downloading the SDK from sun and installing it.

Don't you have to import LinkedList?

Hi Mark,

I did realize the mistake. I corrected the source file, but still i don't get through with compiling. As suggested by others, let me download the latest version of jdk5, install it, and check out.
