数组越界，不知道该怎么解决，求哪位大神告知？

Question

package Mytest;

public class Ages {
public static void main(String[] args) {
Ages hello=new Ages();
int maxscore = hello.getMaxAge();
System.out.println("最大年齡是："+maxscore);
}
public int getMaxAge() {
int[] ages = {18, 23, 21, 19, 25, 29, 17};
int MaxAge = ages[0];
for (int tmp:ages) {
if(MaxAge<ages[tmp]) {
MaxAge=ages[tmp];
}
}
return MaxAge;

}

}

Answer 1

方法一：
public static void main(String[] args) {
Ages hello = new Ages();
int maxscore = hello.getMaxAge();
System.out.println("最大年齡是：" + maxscore);
}
public int getMaxAge() {
int[] ages = { 18, 23, 21, 19, 25, 29, 17 };
int MaxAge = ages[0];
for (int tmp : ages) {
if (MaxAge < tmp) {
MaxAge = tmp;
}
}
return MaxAge;
}

方法二：
public static void main(String[] args) {
    Ages hello = new Ages();
    int maxscore = hello.getMaxAge();
    System.out.println("最大年齡是：" + maxscore);
}
public int getMaxAge() {
int[] ages = { 18, 23, 21, 19, 25, 29, 17 };
int MaxAge = ages[0];
for (int tmp = 0; tmp < ages.length; tmp++) {
    if (MaxAge < ages[tmp]) {
        MaxAge = ages[tmp];
    }
}
return MaxAge;
