import java.util.*;
public class test {
public static void main(String[] args) {
List list = new ArrayList( 100 );
for( int i = 0; i < 10; i ++ ){
list.add( i, String.valueOf( i*31 % 20 ) );
}
Collections.sort( list );
System.out.println( list );
}
}
编译错误:(jdk 1.5.0_01)

Are you sure you are running a 1.5 javac? From
the same command line where you got the error, run "javac -version".

T*****e 发帖数: 361 | 3 Yes, I am sure. I am using eclipse 3.0.2.
There is no other versions of java installed in my pc except jdk/jre 1.5.0_01.

T*****e 发帖数: 361 | 4 刚刚把jdk/jre1.5.0_01删除了,安装了jdk/jre1.5.0_02。
问题还是一样。
看了看eclipse/windows/preferences/java/installed jres,
只有我新安装的jdk1.5.0_02.
可是当我直接用命令行来编译运行这个class时都没有问题。
是不是eclipse并不是用jdk1.5.0_02在编译啊?
头疼……

u****s 发帖数: 2186 | 5 Eclipse 3.0.2 doesn't support JDK1.5, you need to install a plugin
or get 3.1M6
goto Project/Properties/Compliance
set the compile level to 1.5
