问题描述
有没有一个易于遵循的教程,用于在Eclipse中调试Java / J2EE应用程序?
一步一步的指导如何检查未检查和检查的异常?
我一直在尝试在互联网上找到,但没有用。
Is there any easy to follow tutorial for debugging Java / J2EE applications in eclipse? A step by step guide on how to check for unchecked and checked exceptions? I have been trying to find on the internet, but to no use.
推荐答案
Eclipse中的调试器将自动暂停执行(并让您检查变量/步骤/恢复等),如果抛出未捕获的异常。
The debugger in Eclipse will automatically suspend execution (and let you inspect variables/step/resume etc) if an uncaught exception is thrown.
输入例如以下程序...
Enter for instance the following program...
public class Test {
public void methodA() {
methodB("hello");
methodB(null);
}
public void methodB(String s) {
System.out.println(s.substring(2));
}
public static void main(String[] args) {
new Test().methodA();
}
}
...并点击一点错误图标或选择运行 - > 调试为 - > Java应用程序
... and click the little "bug"-icon or choose Run -> Debug As -> Java Application
