Java参数传递数组的使用

数组在函数定义中的使用格式(int\[\]  OrphanCount)

调用的时候一般使用： int\[\] OrphanCountBefore = new int\[2\];  
  
                               theCalledMethod(OrphanCountBefore);

这是公共函数

public void GetOrphanCount(int\[\]  OrphanCount) \{  
         
        int blockStoreOrphanCount = 0;  
        int buildEnvOrphanCount = 0;  
        String prePostText = "after";  
        try \{  
             
                blockStoreOrphanCount = BlockStoreOrphanPurgeCache.getOrphanCount(true, ORPHAN\_FILE, TestConstants.VERBOSE\_ORPHAN\_LOGGING);  
                OrphanCount\[0\] = blockStoreOrphanCount;  
                System.out.println("\*\*\*\*\* Found " + blockStoreOrphanCount + " blockstore orphans ");  
  
             
                buildEnvOrphanCount = BuildEnvironmentOrphanPurge.getOrphanCount(ORPHAN\_FILE, TestConstants.VERBOSE\_ORPHAN\_LOGGING);  
                OrphanCount\[1\] = buildEnvOrphanCount;  
                System.out.println("\*\*\*\*\* Found " + buildEnvOrphanCount + " buildenv orphans ");  
     
             
        \} catch (Exception e) \{ System.out.println("Still end up getting an exception up here"); e.printStackTrace();  
        \}  
    \}

这是调用者的代码

public void testWhileCondEvalsTrue() throws Exception \{  
        int blockStoreOrphanCountBefore = 0;  
        int buildEnvOrphanCountBefore = 0;  
        int\[\] OrphanCountBefore = new int\[2\];  
  
         
        GetOrphanCount(OrphanCountBefore);  
        System.out.println("--------- Starting orphan data collection before running test case:  ---------"+OrphanCountBefore\[0\]);  
         
         
        CreateWhileStep();  
         
        //int OrphanCountAfter\[2\];  
        int\[\]  OrphanCountAfter = new int\[2\];  
        int blockStoreOrphanCountAfter = 0;  
        int buildEnvOrphanCountAfter = 0;  
             
        GetOrphanCount(OrphanCountAfter);  
        System.out.println("--------- Starting orphan data collection after running test case:  ---------"+OrphanCountAfter\[0\]);     
        Assert.assertEquals(OrphanCountBefore\[0\],  
            OrphanCountAfter\[0\],"the blockStoreOrphanCount should be equal before and after run the test case");  
    \}
