public class lazyMan {
private lazyMan(){
System.out.println(Thread.currentThread().getName()+"OK");
}
private static lazyMan lazyman;
public static lazyMan getInstance(){
if(lazyman == null){
lazyman = new lazyMan();
}
return lazyman;
}
public static void main(String[] args) {
for(int i=0;i<10;i++){
new Thread(()->{
lazyMan.getInstance();
}).start();
}
}
}其中的
new Thread(()->{
lazyMan.getInstance();
}).start();改成非lambda運算式，怎么修改？
uj5u.com熱心網友回復：
new Thread() {@Override
public void run() {
lazyMan.getInstance();
}
}.start();
uj5u.com熱心網友回復：
public class lazyManThread extends Thread{@Override
public void run() {
lazyMan.getInstance();
}
}
修改下main方法
lazyManThread thread = new lazyManThread （）；
thread.run();
uj5u.com熱心網友回復：
new Thread() {@Override
public void run() {
lazyMan.getInstance();
}
}.start();

這上面是jdk1.8代碼沒問題，但改為1.6還是有問題，執行緒的lambda還請多指點下

uj5u.com熱心網友回復：
new Thread(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
lazyMan.getInstance();
}
}).start();
