正如标题所说,我有一个数组,我只需要打印索引。我不知道我在做什么。我尝试过几件事。这是最新的。谢谢你的帮助!
public static void evenIndex(int[] array){
int length = array.length;
for (int i = 0; i < length; i++) {
while (array[i] == 0,2,4,6,8){
System.out.print(array[i]);
}
}
}

public static void evenIndex(int[] array){
int length = array.length;
for (int i = 0; i < length; i++) {
if (i%2 == 0){ // make sure i is even
System.out.print(array[i]); // the value of the array @ index i
System.out.print(i); // the index ?
}
}
}
这是你在找什么?

如果你需要打印索引,那么在最后一行打印i而不是array [i]
答案 2 :(得分:0)
如果您只想打印索引,那么您需要做的就是在匹配时打印变量'i',因为这是您当前的位置或数组中的索引:
public static void evenIndex(int[] array){
int length = array.length;
for (int i = 0; i < length; i++) {
while (array[i] == 0,2,4,6,8){
//the following will print eg. index 0 = 0, index 2 = 2,
//is this what is required?
System.out.print('index ' + i + '=' + array[i]);
}
}
}
