How do I fix an "Illegal start of expression" error in Java?
提问by Léo Léopold Hertz ??
I am getting an "Illegal start of expression" error in the following code at the location marked by a comment. How can I correct this error?
我在以下代码中由注释标记的位置收到“非法开始的表达式”错误。我该如何纠正这个错误？
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++;
}
}
}
}
}
}
}

You can't nest methods within one another in Java. Move countIndex()outside the main()method.
您不能在 Java 中将方法相互嵌套。移到方法countIndex()之外main()。

You are missing a closing curly-brace (}) for your main function - place one before the countIndex function declaration. You will also need to call countIndex from main, I presume (edit: elaborated...)
您的主函数缺少右花括号 (}) - 在 countIndex 函数声明之前放置一个。您还需要从 main 调用 countIndex，我想（编辑：详细说明...）
