Java如何打印异常的堆栈？

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; System.out.println("The result is" + result); for (int i = 5; i >= 0; i--) { System.out.println("The value of array is" + array[i]); } } catch (Exception e) { e.printStackTrace(); } } } 

Java

上述代码示例将产生以下结果 -

The result is1
java.lang.ArrayIndexOutOfBoundsException: 5
    at com.yiibai.PrintStackTrace.main(PrintStackTrace.java:13)

示例-2

以下是Java中打印异常堆栈的另一个例子。

package com.yiibai; public class PrintStackTrace2 { public static void main(String[] args) { try { ExceptionFunc(); } catch (Throwable e) { e.printStackTrace(); } } public static void ExceptionFunc() throws Throwable { Throwable t = new Throwable("This is new Exception in Java..."); StackTraceElement[] trace = new StackTraceElement[] { new StackTraceElement("ClassName", "methodName", "fileName", 5) }; t.setStackTrace(trace); throw t; } } 

Java

上述代码示例将产生以下结果 -

java.lang.Throwable: This is new Exception in Java...
    at ClassName.methodName(fileName:5)
