枚举IO区分大小写.不同的操作系统对文件名的区分大小写具有不同的规则.例如,Windows对文件命名不区分大小写,而Unix区分大小写. IOCase捕获该差异,提供枚举以控制应如何执行文件名比较.它还提供了使用枚举进行比较的方法.
枚举声明
以下是 org.apache.commons的声明. io.IOCase 枚举和减号;
public enum IOCase extends Enumimplements Serializable
IOCase枚举的例子
IOTester.java
import java.io.IOException;import org.apache.commons.io.IOCase;public class IOTester { public static void main(String[] args) { try { usingIOCase(); } catch(IOException e) { System.out.println(e.getMessage()); } } public static void usingIOCase() throws IOException { String text = "Welcome to TutorialsPoint. Simply Easy Learning."; String text1 = "WELCOME TO TUTORIALSPOINT. SIMPLY EASY LEARNING."; System.out.println("Ends with Learning (case sensitive): " + IOCase.SENSITIVE.checkEndsWith(text1, "Learning.")); System.out.println("Ends with Learning (case insensitive): " + IOCase.INSENSITIVE.checkEndsWith(text1, "Learning.")); System.out.println("Equality Check (case sensitive): " + IOCase.SENSITIVE.checkEquals(text, text1)); System.out.println("Equality Check (case insensitive): " + IOCase.INSENSITIVE.checkEquals(text, text1)); } }
输出
它将打印以下结果.
Ends with Learning (case sensitive): falseEnds with Learning (case insensitive): trueEquality Check (case sensitive): falseEquality Check (case insensitive): true
