Create a thread in the first way: each thread is dealing with a different resource
Each thread corresponds to 20 movie tickets, and there is no relationship between them, which means that each thread is equal and has no precedence
Class Tc extends Thread
{
private int tickets = 20;//Each thread sells 20 tickets each

public String name;
Public Tc (String name)
{
THIS.name = name;
}
public void Run ()
{
while (Tickets > 0)
{
System.out.printf ("%s window is selling%d tickets \ n", name,tickets);
Tickets--;
}
}
}
public class Zhang3
{
public static void Main (string[] args)
{
TC T1 = new TC ("Old person window----");
T1.run ();//implement a window to sell tickets

TC T2 = new TC ("-------Children's Window");
T2.run ();//Different class objects whose properties occupy a different memory space, which is fundamental

TC T3 = new TC ("---Middle-aged window---");
T3.run ();
}
}
/*

Create the thread in the second way: same as each thread can handle different resources
Class Tc implements Runnable
{
private int tickets = 20;//Each thread sells 20 tickets each

public String name;
Public Tc (String name)
{
THIS.name = name;
}
public void Run ()
{
while (Tickets > 0)
{
System.out.printf ("%s window is selling%d tickets \ n", name,tickets);
Tickets--;

}
}
public class Zhang4
{
public static void Main (string[] args)
{
TC AA = new TC ("Old person window----");
thread T1 = new thread (AA);
T1.run ();//implement a window to sell tickets

TC BB = new TC ("-------Children's Window");
Thread t2 = new Thread (BB);
T2.run ();//Different class objects whose properties occupy a different memory space, which is fundamental

TC CC = new TC ("---Middle-aged window---");
thread t3 = new Thread (CC);
T3.run ();
}

Create a thread in the second way: multiple threads are working on the same resource
Class Tc implements Runnable
{
private int tickets = 10000;//3 threads handle 100 tickets altogether

public void Run ()
{
while (true)
{
Synchronized ("Zhang")
{
if (Tickets > 0)
{
System.out.printf ("%s window is selling%d tickets \ n", Thread.CurrentThread (). GetName (), tickets);
Tickets--;

}
Else
Break
}
}
}
}
public class Zhang5
{
public static void Main (string[] args)
{
TC AA = new TC ();
thread T1 = new thread (AA); AA Object
T1.setname ("Old person window");
T1.start ();//implement a window to sell tickets

Thread t2 = new Thread (AA); AA Object
T2.setname ("Children's Window");
T2.start ();//Different class objects whose properties occupy a different memory space, which is fundamental

thread t3 = new thread (AA); AA Object
T3.setname ("Middle-aged window");
T3.start ();
}
}
/*
The result is: three ticket offices to handle 1000 tickets together
*/
/* Integrated: The implementation of the Runnable interface has unparalleled advantages over the extended thread class.
This approach is not only beneficial to the robustness of the program, so that the code can be shared by multiple threads, and the code and data resources are relatively independent,
This makes it particularly suitable for multiple threads with the same code to handle the same resource situation.
In this way, the thread, code and data resources are effectively separated, which embodies the idea of object-oriented programming.
As a result, almost all multithreaded programs are done by implementing the Runnable interface. */
