问题描述
我正在对 Java 7 的新功能进行 POC.我有在 switch 语句中使用 String 的代码,它可以工作.我也想让它在不区分大小写的情况下工作.有没有办法在 String 上使用 ignoreCase 进行检查?
I am doing a POC on Java 7 new features. I have code to use String in switch statement and it works. I want to make it work in case insensitive also. Is there a way to check out with ignoreCase on String?
package com.java.j7;
public class Test {
final private String _NEW ="NEW";
final private String _PENDING = "PENDING";
final private String _CLOSED = "CLOSED";
final private String _REJECTED ="REJECTED";
public static void main(String... strings){
Test j = new Test();
j.processItem("new");
j.processItem("pending");
j.processItem("closed");
j.processItem("rejected");
}
void processItem(String s){
switch (s) {
case _NEW:
System.out.println("Matched to new");
break;
case _PENDING:
System.out.println("Matched to pending");
break;
case _CLOSED:
System.out.println("Matched to closed");
break;
case _REJECTED:
System.out.println("Matched to rejected");
break;
default:
System.out.println("Not matching any more");
break;
}
}
}
推荐答案
不,但你可以打开 s.toUpperCase()
.所以:
no, but you could switch on s.toUpperCase()
. so:
switch (s.toUpperCase()) {
//same as before
}
虽然我们在吹毛求疵,但您最好将英文语言环境中的大写字母改为 避免土耳其语问题
and while we're nitpicking, you better upper-case things in the english locale to avoid issues with turkish
