Two ways to implement java-based threading

Process refers to an in-memory running application, each process has its own separate piece of memory space, a process can start multiple threads! Threads are always part of a thread, and threads in a process share the memory of the process

note: for java, The run () method has nothing special. Like the main () method, it is just a new thread that knows the method name (and Signature) of the Call. therefore, It is legal to raise the Run method on runnable or Thread. But does not start a new thread, start a new thread to call the start () method

There are two ways to implement threads in Java: 1. inherit the thread class

 packageunit_fifteen; public classTestthreadextendsThread {PrivateString name;  publictestthread (String Name) { this. Name =name; } @Override public voidRun () { for(inti = 0; I < 5; i++) {             for(intj = 0; J < 2; J + +) {System.out.println (name+ ":" +i); }        }    }    //inherit the thread class     public Static voidmain (string[] Args) {//You can create a thread without a nameTestthread tone =NewTestthread ("ah san"); Testthread Ttwo=NewTestthread ("john doe");        Tone.start ();    Ttwo.start (); }} 

2. Implement runnable interface

 packageunit_fifteen; public classTestrunnnableImplementsRunnable { public Static voidmain (string[] Args) {//Implement the Runnable interface, you can create a thread that is not namedTestrunnnable Dsone =NewTestrunnnable ("ah san"); Testrunnnable Dstwo=NewTestrunnnable ("john doe"); //creates a thread object as a parameter to an object of a class that implements the Runnable interfaceThread tone =NewThread (dsone); Thread Ttwo=NewThread (dstwo);        Tone.start ();    Ttwo.start (); }    PrivateString name;  publictestrunnnable (String Name) { this. Name =name; } @Override public voidRun () { for(inti = 0; I < 5; i++) {             for(intj = 0; J < 2; J + +) {System.out.println (name+ ":" +i); }        }    }}
