如何解决Java中的“非法表达式开始”错误?
问题描述:
我在下面的代码中标注了注释的位置出现“非法表达式开始”错误。我该如何纠正这个错误?如何解决Java中的“非法表达式开始”错误?
class planetUfo {
public static void main (String[] args) {
// having data for counting the index
char letters[] = {'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
// initial data
String[] groups = {"COMETQ", "ABSTAR"};
String[] comets = {"HVNGAT", "USACO"};
// Problem here!
// to count the index
private void countIndex (String group, String comet) {
// I get here "illegal start of an expression"
// to have two words in the array
char[] name = { group, comet };
// to go though the words one by one in the block of the array
int k = 0;
for (int k : name[k]) {
// to save each letter to an array
char[] words = name[k].toCharArray();
int sum = 1;
// to loop through each character in the word
for (int i = 0; i < words.length; i++) {
// to loop through each necessary character in the alphabets
int j = 0;
for (int j = 0; j < letters.length; j++) {
while (letters[j] !== words[i]) {
// to look the index of the letter in the word
int indexNumber = j;
sum = sum * (indexNumber + 1);
index[k] = sum;
j++;
}
}
}
}
}
}
}
答
您不能在Java中相互嵌套方法。在main()
方法之外移动countIndex()
。
答
您错过了主函数的关闭花括号(}) - 在countIndex函数声明之前放置一个。您还需要从main调用countIndex,我推测(编辑:详细说明...)
