java进行error捕获和处理示例(java异常捕获)

下面给个小例子，来验证一下error的捕获。

public class testcatcherror extends error{

    private static final long serialversionuid = -351488225420878020l;

    public testcatcherror(){
        super();
    }

    public testcatcherror(string msg){
        super(msg);
    }

    public static void main(string[] args) {
        try {
            throw new testcatcherror("test catch error");
        } catch (throwable t) {
            system.out.println("step in the catch ~");
            t.printstacktrace();
        }
    }
}

运行结果：

step in the catch ~
testcatcherror: test catch error
at testcatcherror.main(testcatcherror.java:23)
