java 值传递还是引用传递

public class QQ {

    public static void main(String[] args) {

        String[] strArray = new String[] { "1", "2" };

        processOne(strArray);
        System.out.println(strArray[0] + "  " + strArray[1]);

        processTwo(strArray);
        System.out.println(strArray[0] + "  " + strArray[1]);
    }

    public static void processOne(String[] strArray) {
        strArray = new String[] { "3", "4" };
    }

    public static void processTwo(String[] strArray) {
        strArray[0] = "3";
        strArray[1] = "4";
    }

}
