};
public void add(String s) {
/* code to add something to contents here */
};
public void reverse() {
/* code to reverse the contents here */
};
}
public class GroupUser extends Thread {
Group group;
public GroupUser(Group g) {
group = g;
}
public void changeGroup() {
/* code that calls group.add() several times then group.reverse() */
}
public void run() {
for (int i = 0; i < 10; i++) changeGroup();
}
}
public static void main(String args[]) throws InterruptedException {
Group g = new Group();
new GroupUser(g).start();
new GroupUser(g).start();
new GroupUser(g).start();
}
Which of the following changes could you make to the code to prevent the three threads
started by main from interfering with each other’s use of the shared Group instance
(provided by main) in GroupUser.changeGroup?
Question Number 18
change the call to changeGroup in GroupUser.run to:synchronized(group) {
changeGroup();
}
change the call to changeGroup in GroupUser.run to:synchronized(this) {
changeGroup();
----------
Iterator list= new iterator()
list = vect1.iterator()
while(list.hasNext())
{
String element = (String)list.next();
System.out.print(element);
}
Iterator list= new iterator()
list = vect1.iterator()
while(vect1.hasNext())
{
String element = (String)vect1.next();
System.out.print(element);
}
Iterator list= vect1.iterator()
while(list. vect1.hasNext())
{
String element = (String)list. vect1.next();
System.out.print(element);
}

第一部分Baseline IT Aptitude 40分钟 又可以细分为六个小部分 每个小部分单独计时每个小部分之间
可以take break

第二部分性格测试 155道选择题 不计时 外企的性格测试都差不多 不必多说按自己的实际情况填就好了
第一部分的六小部分如下：
数学：10分钟10道题 不同于SHL 不是图表计算 而是类似中学应用题一样的计算 但是是英文题干的 注意
可以适当的skip 因为这里skip并不代表放弃 做完后面的题后电脑会自动返回之前skip的题让你继续作答
