Java比较字符串与子字符串

Question

I was having some problem when trying to compare strings in Java.

Example of list of words to be compared:

angry, berry, you, young, your, apple, orange, yeast

When user entered 'y' character, the results I am getting:

angry, berry, you, young, your, yeast

By right it supposed to return these only:

you, young, your, yeast

The next time when the user entered 'you', the 'yeast' should be filtered out.

Here is my code:

for (String v : words) {
        if (v.toLowerCase().contains(input.toLowerCase())){
            System.out.print("MATCHING WORDS " + v);
        }
    }

Any ideas? Thanks!

Answer 1

使用startsWith()而不是contains() 。

Answer 2

for (String v : words){
    String word = v.toLowerCase();
    if(word.substring(0,1).equals(input.toLowerCase())){
        System.out.print("MATCHING WORDS " + v);
    }
}
