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");

}
