Java中遍历数组的三种方法
public class For_List{
public static void main (String args[]){
int a[] = {1,3,5,7,9,11};
//普通for 循环遍历数组;
for(int i = 0;i<a.length;i++){
System.out.println("a["+(i)+"]="+a[i]);
}
a[0] = 999; //修改数组的值;
a[2] = 888; //修改数组的值;
//for-each 遍历数组;
for (int aa:a){
System.out.println(aa+" ");
}
//jdk自带方法遍历数组;
System.out.println(java.util.Arrays.toString(a));
}
}
