Why ?

 
public class synchronize extends Thread 
{ 
    StringBuffer sb; 
    public void run() 
    { 
 
        //synchronized(sb) 
 
        { 
            for(int i=1;i<=100;i++) 
            { 
                System.out.print(sb); 
            } 
 
            System.out.println(); 
 
            //Increment the sb in StringBuffer 
            char temp= sb.charAt(0); 
            ++temp; 
            sb.setCharAt(0,temp); 
        } 
 
    } 
    public synchronize(StringBuffer sb) 
    { 
        this.sb=sb; 
 
    } 
    public static void main(String [] args) 
    { 
        StringBuffer sbm=new StringBuffer("A"); 
        new synchronize(sbm).start(); 
        new synchronize(sbm).start(); 
        new synchronize(sbm).start(); 
    } 
}
