Question

Type, Compile, Run all syntactically complete or mostly complete example code .You may need to change some syntax to make them compile and run

import java.io.*; import java.lang.*; import java.util.*;

class MyThreadExampleMutex{
public static void main(String[] args) {

new HelloThread (1). start ();
new HelloThread (2). start ();
new HelloThread (3). start (); System.out.print("Global.buffer Content = "); for (int i = 0; i < 9; i++) {

System.out.print(Global.buffer[i] + "; ");

}} }

class Global {
public static int[] buffer = new int[15]; public static int index = 0;

}
class HelloThread extends Thread {

int threadID; HelloThread(int ID) {

this.threadID = ID; }

public void run() {
for (int i = 0; i < 3; i++) {

Global.buffer[Global.index] = this.threadID;

Global.index++; }

} // run
} // end Thread

public class MyThreadExampleMutex {

public static void main(String[] args) {

new HelloThread(1).start();

new HelloThread(2).start();

new HelloThread(3).start();

System.out.print("Global.buffer Content = ");

for (int i = 0; i < 9; i++) {

System.out.print(Global.buffer[i] + "; ");

}

}

}

class Global {

public static int[] buffer = new int[15];

public static int index = 0;

}

class HelloThread extends Thread {

int threadID;

HelloThread(int ID) {

this.threadID = ID;

}

public void run() {

for (int i = 0; i < 3; i++) {

Global.buffer[Global.index] = this.threadID;

Global.index++;

}

} // run

} // end Thread
