source-code: public class A { public A() {} private static void printStackTrace() { StackTraceElement[] stackElements = new Throwable().getStackTrace(); if(stackElements != null) { for(int i = 0; i < stackElements.
在Java编程中,如何打印异常的堆栈? 此示例显示如何使用异常类的printStack()方法打印异常的堆栈. package com.yiibai; public class PrintStackTrace { public static void main(String args[]) { int array[] = { 20, 20, 40 }; int num1 = 15, num2 = 10; int result = 10; try { result = num1 / num2; S
public class Demo { /* * Java编程,打印昨天的当前时刻 */ public static void main(String[] args){ Calendar cal = Calendar.getInstance(); cal.add(Calendar.DATE, -1); Date date = cal.getTime(); SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:s
Exception e = new Exception("this is a log"); e.printStackTrace(); //延迟才可以看出效果 Thread.currentThread().sleep(1000); System.out.println("-------------以上是异常详细信息----------------"); System.out.println("打印异常1:"+e.toString()); Strin
一.打印效果 二.实现代码汇总 为了方便初学者对代码的理解,建议熟练t1到t5为各种三角的打印,然后再进行菱形的打印实现. package circulationDemo; import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("请输入要打印的行数:"
