我正在研究对象数组,直到没有元素为止,我才能获取元素。例如Object[] elements={"Apple","Orange","Grape","Mango","Banana"};
我可以按索引获取元素,但是当我超出索引长度时。例如,这里有5个元素最后将由elements [4]访问,但是如何检查elements [5],elements [6]或不
最佳答案
例如,
Object[] elements = {"Apple","Orange","Grape","Mango","Banana"};
Object obj = null;
int elementsLength = elements.length;
int i = 10;
if (i < elementsLength) {
obj = elements[i];
} else {
System.out.println("Oops!.. Out of index!");
}
if (obj != null) {
System.out.println(obj);
}
