Apache Commons IO IOCase

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来执行比较的方法。

Enum宣言

以下是 org.apache.commons.io.IOCase Enum 的声明-

public enum IOCase
   extends Enum<IOCase> implements Serializable

IOCase Enum的示例

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 CodingDict. Simply Easy Learning.";
      String text1 = "WELCOME TO CodingDict. 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): false
Ends with Learning (case insensitive): true
Equality Check  (case sensitive): false
Equality Check  (case insensitive): true
