java進行error捕獲和處理樣本(java異常捕獲)_java

下面給個小例子，來驗證一下error的捕獲。

複製代碼 代碼如下:

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();
        }
    }
}

運行結果：

複製代碼 代碼如下:

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