可以返回String数组

Question

是否有可能在java中创建一个返回String[]的方法？

Answer 1

Yes, but in Java the type is String[] , not string[] . The case is important.

For example a method could look something like this:

public String[] foo() {
    // ...
}

Here is a complete example:

public class Program
{
    public static void main(String[] args) {
        Program program = new Program();
        String[] greeting = program.getGreeting();
        for (String word: greeting) {
            System.out.println(word);
        }
    }

    public String[] getGreeting() {
        return new String[] { "hello", "world" };
    }
}

Result:

hello
world

    return new String[5];
}

Answer 3

String[] dummyMethod()
{
    String[] s = new String[2];
    s[0] = "hello";
    s[1] = "world";
    return s;
}

Answer 4

public String[] returnStringArray()
{
    return new String[] { "a", "b", "c" };
}

Do you have a more specific need?

public String [] getSomeStrings() {
    return new String [] { "Hello", "World" };
}
