分析下面程序，写出程序执行结果；
public class Testp {
public static void test(boolean test) {
test = ! test;
System.out.println("In test(boolean) : test = " + test);
}
public static void main(String[] args) {
boolean test = true;
System.out.println("Before test(boolean) : test = " + test);
test(test);
System.out.println("After test(boolean) : test = " + test);
}
}
