有数组a[n]用java代码将数组元素顺序颠倒

public static void main(String[] args) {

//String a[] = new String[12];

String a[] = new String[11];

// 赋值a[n]

System.out.print("a[n]元素初始值依次为：");

for (int i = 0; i a.length; i++) {

a[i] = String.valueOf(i);

System.out.print(a[i] + " ");

}

System.out.println(""); // 换行

int length = a.length;

// a[n]元素顺序倒转

System.out.print("a[n]元素倒转后依次为：");

for (int i = 0; i length/2; i++) {

String tmp = a[i];

a[i]=a[length-1-i];

a[length-1-i]=tmp;

}

for (int i = 0; i a.length; i++) {

System.out.print(a[i] + " ");

}
