Commons Io 简明教程

Apache Commons IO - IOCase

IO 大小写敏感性的枚举。不同的操作系统对文件名的区分大小写有不同的规则。例如，Windows 对于文件命名不区分大小写，而 Unix 则区分大小写。IOCase 捕获该差异，提供了一个枚举来控制如何执行文件名比较。它还提供使用枚举执行比较的方法。

Enum Declaration

下列是 org.apache.commons.io.IOCase 枚举的声明 −

public enum IOCase
   extends Enum<IOCase> implements Serializable

Example of IOCase Enum

IOCase 枚举的一个示例如下 −

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));
   }
}

Output

它会打印以下结果 −

Ends with Learning (case sensitive): false
Ends with Learning (case insensitive): true
Equality Check (case sensitive): false
Equality Check (case insensitive): true
