JBuilder中的JDK问题,怎么解决.!怎么没理我啊??????????????????????????
我把JBuilder的JDK设为我安装的C:/Java/jdk1.6.0_01可是为什么我写public class ColorBorder extends JFrame //显示JFrame 有错
报错:cannot access javax.swing.JFrame,bad class file: C:/Java/jdk1.6.0_01/jre/lib/rt.jar/javax/swing/JFrame.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 5 (5:34)
可是这个JDK我是从官方网站上下的.为什么啊??????????????
