如何将此 Java For Each 循环转换为常规 For 循环？ [复制]

Question

我正在尝试将这个 for each 转换为 for 循环。我该怎么做？

这是我正在使用的代码

for (char character: word.toCharArray()) {
                    character = Character.toUpperCase(character);
                    
                    if (character >= 'A' && character <= 'Z') {
                        count[character - 'A']++;
                    }
                    
                }

提前致谢

就是这样：

char[] source = word.toCharArray();
for (int i = 0; i < source.length; i ++) {
     char character = Character.toUpperCase(source[i]);
     if (character >= 'A' && character <= 'Z') {
         count[character - 'A']++;
     }
}
