java怎样获取一维数组的长度？
public class Demo {
public static void main(String[] args){
String[] array = {"求","数","组","的","长","度","！"};
int length = array.length;
System.out.println("数组array的长度为：" + length);
}

看看例子吧
public class Array {
public static void main(String[] args) {
int a[]={0,1,2,3,4,5}; //声明并初始化有6个元素的数组
int b=a.length; //得到数组的长度
System.out.println("数组a的长度为："+b);
}

数组名.length()2008-12-31
用length（）方法2008-12-31
.length()2008-12-31
