ArrayIndexOutOfBoundsException 是Java中常见的运行时异常之一,它发生在尝试访问数组中不存在的索引时。以下是关于这个异常的基础概念、原因以及解决方法: 基础概念 ArrayIndexOutOfBoundsException:当程序试图访问数组中不存在的索引时抛出的异常。 原因 索引超出范围:尝试访问的数组索引小于0或者大于等于数组的长...
下面是一个简单的Java代码示例,演示了如何避免ArrayIndexOutOfBoundsException异常: public class ArrayExample { public static void main(String[] args) { int[] array = new int[5]; // 正确访问数组元素 array[0] = 1; array[4] = 5; // 错误访问数组元素(会抛出ArrayIndexOutOfBoundsException异常) ...
java public class ArrayAccessExample { public static void main(String[] args) { int[] numbers = {1, 2, 3}; int index = 2; // 假设这是从某处获取的索引值 // 检查索引是否在合法范围内 if (index >= 0 && index < numbers.length) { int value = numbers[index]; Syst...
public class Example { public static void main(String[] args) { int[] array = new int[5]; int index = 10; try { int value = array[index]; System.out.println("数组值: " + value); } catch (ArrayIndexOutOfBoundsException e) { System.out.println("数组索引越界异常:" + e.getMessa...
下面是一个简单的Java代码示例,演示了ArrayIndexOutOfBoundsException的产生: publicclassArrayIndexOutOfBoundsExample{publicstaticvoidmain(String[]args){int[]array={1,2,3};System.out.println(array[3]);// 访问索引为3的元素,超出了数组的索引范围}} ...

在游戏中,文本是必不可少的元素之一,通常创建了一个文本内容,还有可能会随时更改它,创建一个文本的方法如下(摘至Andengine源码中的TextExample.java): this.mFont = FontFactory.create(this.getFontManager(),this.getTextureManager(), 256, 256, Typeface.create(Typeface.DEFAULT, Typeface.BOLD), 32);this....
Usually, one would come across “java.lang.ArrayIndexOutOfBoundsException: 4” which occurs when an attempt is made to access (4+1)fifth element of an array, despite the size of array being less than five.Following is an example program that could produce this exception....
When you learn Java,Some details of the small problems tend to be very confusing,When in receive parameters, for example。 If your program needs to receive arguments in order to run,And you did not give the default parameters,That can cause this error: ...
