本文介绍了一个关于如何在Java函数中使用数组的实例。通过一个公共函数GetOrphanCount来获取并返回两个不同环境下的孤儿计数。此外，还展示了如何在测试函数中调用该公共函数，并比较测试前后孤儿计数的变化。

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");
}
