线程demo3

package Thread;  import java.util.Date;  public class ThreadDemo3 {  public static void main(String[] args) {   Thread thread1 = new MyThread3("   T1");   Thread thread2 = new MyThread3("T2");   thread1.setPriority(Thread.NORM_PRIORITY   3);   thread2.setPriority(Thread.NORM_PRIORITY - 3);   thread1.start();   thread2.start();  } }  class MyThread3 extends Thread {  MyThread3(String name) {   super(name);  }   @Override  public void run() {   for (int i = 0; i < 100; i  ) {    System.out.println(getName()   i);   }  } }

结果如下：

   T10 T20    T11 T21    T12 T22    T13 T23    T14 T24    T15 T25    T16 T26    T17 T27    T18 T28    T19 T29    T110 T210    T111    T112    T113 T211    T114 T212    T115 T213    T116 T214    T117 T215    T118 T216    T119 T217    T120 T218    T121 T219    T122 T220    T123 T221    T124 T222    T125 T223    T126 T224    T127 T225    T128 T226    T129 T227    T130 T228    T131 T229    T132 T230    T133 T231    T134    T135    T136    T137 T232    T138 T233    T139 T234    T140 T235    T141 T236    T142 T237    T143 T238    T144    T145 T239    T146 T240    T147 T241    T148 T242    T149 T243    T150 T244    T151 T245    T152 T246    T153 T247    T154 T248    T155 T249    T156 T250    T157 T251    T158 T252    T159 T253    T160 T254    T161 T255    T162 T256 T257 T258    T163    T164    T165    T166    T167    T168    T169    T170    T171    T172    T173    T174 T259    T175 T260    T176 T261    T177 T262    T178 T263    T179 T264    T180 T265    T181 T266    T182 T267    T183 T268    T184 T269    T185 T270    T186    T187    T188    T189    T190    T191    T192    T193    T194    T195    T196    T197    T198    T199 T271 T272 T273 T274 T275 T276 T277 T278 T279 T280 T281 T282 T283 T284 T285 T286 T287 T288 T289 T290 T291 T292 T293 T294 T295 T296 T297 T298 T299 

该程序主要将两个线程设置为不同的优先级，从而分配给它们不同的执行时间（优先级高的程序分配更多的执行时间，反之亦然）。从结果中可以看出线程T一是优先执行。
