mark一下，不停的看看notify和wait的没有理解
class Printer
{
int index=0;
//输出奇数
public synchronized void printA(int a)
{
while(index%2==0)
{
try {
this.wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
index++;
System.out.println(a);
notify(); }
public synchronized void printB(char b)
{
while(index%2!=0)
{
try {
this.wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
index++;
System.out.println(b);
notify(); } }
