我们可以通过synchronized块来同步特定的静态或非静态方法。要想实现这种需求必须为这些特性的方法定义一个类变量，然后将这些方法的代码用synchronized块括起来，并将这个类变量作为参数传入synchronized块。下面的代码演示了如何同步特定的类方法：
001
package
mythread;
002
003 public class SyncThread extends Thread
004 {
005 private static String sync = "" ;
006 private String methodType = "" ;
007
008 private static void method(String s)
009 {
010 synchronized (sync)
011 {
012
sync
=
s;
013 System.out.println(s);
014 while ( true );
015 }
016 }
017 public void method1()
018 {
019 method( " method1 " );
020 }
021 public static void staticMethod1()
022 {
023 method( " staticMethod1 " );
024 }
025 public void run()
026 {
027 if (methodType.equals( " static " ))
028 staticMethod1();
029 else if (methodType.equals( " nonstatic "
002
003 public class SyncThread extends Thread
004 {
005 private static String sync = "" ;
006 private String methodType = "" ;
007
008 private static void method(String s)
009 {
010 synchronized (sync)
011 {
013 System.out.println(s);
014 while ( true );
015 }
016 }
017 public void method1()
018 {
019 method( " method1 " );
020 }
021 public static void staticMethod1()
022 {
023 method( " staticMethod1 " );
024 }
025 public void run()
026 {
027 if (methodType.equals( " static " ))
028 staticMethod1();
029 else if (methodType.equals( " nonstatic "
