Consult the rewrite lambda expressions-CodePudding

 public class lazyMan {

Private lazyMan () {
System. Out. Println (Thread. CurrentThread (). The getName () + "OK"); 
} 

Private static lazyMan lazyMan; 

Public static lazyMan getInstance () {
If (lazyman==null) {

Public static void main (String [] args) {

LazyMan. GetInstance (); 
}).start(); 
}

}

The

 new Thread (() - & gt; {
LazyMan. GetInstance (); 
}).start();

to the lambda expressions, how to change?

CodePudding user response:

New Thread () {
@ Override
Public void the run () {
LazyMan. GetInstance ();
}
}. The start ();

CodePudding user response:

Public class lazyManThread extends Thread {
@ Override
Public void the run () {
LazyMan. GetInstance ();
}
}

Modify the main method under
LazyManThread thread=new lazyManThread ();
Thread. The run ();

CodePudding user response:

New Thread () {
@ Override
Public void the run () {
LazyMan. GetInstance ();
}
}. The start ();

CodePudding user response:

refer to the second floor KeepSayingNo response:

public class lazyManThread extends Thread {
@ Override
Public void the run () {
LazyMan. GetInstance ();
}
}

Modify the main method under
LazyManThread thread=new lazyManThread ();
Thread. The run ();

This is jdk1.8 code above no problem, but still have problem, instead of 1.6 thread under the lambda also please advise of

reference 1/f O reply: happiness is

new Thread () {
@ Override
Public void the run () {
LazyMan. GetInstance ();
}
}. The start ();

This is jdk1.8 code above no problem, but still have problem, instead of 1.6 lambda also please advice more threads
