我知道循环是如何工作的，但我不确定如何检查在这种情况下迭代的字符串的最后一个索引。这是一个例子:

String words = "Apple gum fruit red orange triangle";
for(String foo : words.split("\\s+"){
    //How would I get the index of foo at any given point in the loop
 }

Answer 1

String   sentence = "Apple gum fruit red orange triangle";
String[] words    = sentence.split("\\s+");
for( int i = 0; i < words.length; ++i ) {
   String foo = words[i];
   // i is the index
}
