JRun下的错误怎么调试

[grand1984]

错误1：No method named "split" was found in type "java/lang/String".Content=Content.replaceAll("\n" , "<br>");;

错误2：String[] strs = str.split("\n");
Error: No method named "split" was found in type "java/lang/String".

错误3：error：java.lang.NullPointerException


错误4：由于当前未访问行，因此结果集为IDLE.

条件：JDK下面的lang/String中有replaceAll和split两个方法

你的JDK版本太低了,1.4及之后的版本才支持split(),replaceAll()

还有，在CSDN问问题，如果得到正确答案了，要学会结贴。
