Suppose you have two mysql instances  c:\mysq1 and c:\mysql2 1- create file c:\mysql1\my.cnf add the following lines [mysqld] datadir = C:/mysql1/data port = 3308     2- create file c:\mysql2\my.cnf add the following lines   [mysqld] datadir = C:/mysql2/data port = 3309    3-now run the first instance    cd c:\mysql1\bin mysqld --defaults-file=c:\mysql1\my.cnf     4-open another command and run the second instance     cd c:\mysql2\bin mysqld --defaults-file=c:\mysql2\my.cnf finsihed ;)

This  block of code detects if mysql  database process  is running or not String line; try {             Process proc = Runtime.getRuntime().exec("wmic.exe");             BufferedReader input = new BufferedReader(new InputStreamReader(proc.getInputStream()));             OutputStreamWriter oStream = new OutputStreamWriter(proc.getOutputStream());             oStream .write("process where name='mysqld.exe'");             oStream .flush();             oStream .close();             while ((line = input.readLine()) != null) {                 // Here detects if mysqld process is running             }             input.close();         } catch (IOException ioe) {             ioe.printStackTrace();         }   This block of code starts mysql service Process p = new ProcessBuilder("c:/mysql/bin/mysqld", "").start();   And  you may use  p.destroy(); if you want to Stop it

// An incorrect implementation of a producer and consumer. class Q { int n; synchronized int get() { System.out.println("Got: " + n); return n; } synchronized void put(int n) { this.n = n; System.out.println("Put: " + n); } } class Producer implements Runnable { Q q; Producer(Q q) { this.q = q; new Thread(this, "Producer").start(); } public void run() { int i = 0; while(true) { q.put(i++); } } } class Consumer implements Runnable { Q q; Consumer(Q q) { this.q = q; new Thread(this, "Consumer").start(); } public void run() { while(true) { q.get(); } } } class PC { public static void main(String args[]) { Q q = new Q(); new Producer(q); new Consumer(q); System.out.println("Press Control-C to stop."); } } Although the put( ) and get( ) methods on Q are synchronized, nothing stops the producer from overrunning the consumer, nor will anything stop the consumer from consuming the same queue value twice. Thus, you get the e
