java 异常测试

【代码示例】

package com.linhuaming.test;

import com.sun.org.slf4j.internal.Logger;
import com.sun.org.slf4j.internal.LoggerFactory;

/**
 * 异常测试
 */
public class ExceptionTest {
    // private final static Logger logger = LoggerFactory.getLogger(ExceptionTest.class);
    private final static Logger logger = LoggerFactory.getLogger(ExceptionTest.class);

    /**
     * 主方法
     * @param args
     */
    public static void main(String[] args) {
        // UserTest.methodA();


        System.out.println("main()");
        try{
            methodA();
        }catch (Exception e){
            logger.error(e.getMessage(),e);
            throw new RuntimeException("执行methodA()方法失败");
        }
    }

    public static void methodA(){
        System.out.println("methodA()");
        try{
            methodB();
        }catch (Exception e){
            logger.error(e.getMessage(),e);
            throw new RuntimeException("执行methodB()方法失败");
        }
    }

    public static void methodB(){
        System.out.println("methodB()");
        try{
            methodC();
        }catch (Exception e){
            logger.error(e.getMessage(),e);
            throw new RuntimeException("执行methodC()方法失败");
        }
    }

    public static void methodC(){
        System.out.println("methodC()");
        int x = 1;
        int y = 0;
        double z = x/y;
        System.out.println(z);
    }

}

【运行结果】

main()
methodA()
methodB()
methodC()
