JDK1.4 换成JDK1.5的问题

[llin998]

我把JDK1.4 换成JDK1.5的问题,一个普通的程序
public class TestSend {
public TestSend() {
}
public static void main(String[] args) {
java.util.List list = new java.util.ArrayList();

出现错误如下:
"TestSend.java": D:\cernet work\TestMO\TestMO\src\TestSend.java:8: cannot access java.lang.Object,bad class file: C:\Program Files\Java\jdk1.5.0_05\jre\lib\rt.jar(java/lang/Object.class),class file has wrong version 49.0, should be 48.0,Please remove or make sure it appears in the correct subdirectory of the classpath. at line 8


请帮忙分析分析

jdk 1.5 需要申明ArrayList的容纳类型。

我已经解决了,是在JBUILDER里的编译选项的问题!

也没有参与的,我就给分了，以后这种问题不来这里问了!
