String Splitting Error In Android

Question

Hi Android Developers,

I have a problem with string splitting in android in tells that change the java compliance to JRE 1.7 when i changed the compliance error occurs because it works only in api level 19

   String st="a,b,c,d";
   String[] temp=st.split(",");
   for(int i=0;i<temp.lenght;i++)
   {
       switch(temp[i])
       {
           case "a":
                   //print something
                   break;
           case "b":
                  //print something
                  break;
           case "c":
                 //print something
                  break;
           case "d":
                 //print something
                 break;
          default:
                 //print something
       }
   }

The error is in the switch statement, how can I solve it I am developing in 2.3 devices?

The error:

[2014-08-22 11:47:26 - text] Using 1.7 requires compiling with Android 4.4 (KitKat); currently using API 8

Switching strings is implemented in Java 1.7+ For the API lvl 19 error - i don't see here any Android specific code. — localhost, Aug 22 '14 at 06:13
Just replace your switch statement with set of else-if statements Switch by String was introduced in JDK 1.7 while Android SDK based on JDK 1.6 — Viacheslav, Aug 22 '14 at 06:15
1.6 doesn't allow you to pass strings in switch statement. Please change it. — Aniruddha, Aug 22 '14 at 06:18

To resolve: Using 1.7 requires compiling with Android 4.4 (KitKat); currently using API 8

Try Project --> Properties --> Java Compiler --> Compliance Level --> 1.6
After setting compliance level, clean the project. If required, restart eclipse.

Also, as James pointed out, your for loop should be i<temp.length (Spelling mistake should be corrected)

You have made a spelling error:

for(int i=0;i<temp.lenght;i++)
                    ^^

It should say length not lenght

That's a problem, but not the problem in question. – Michael Yaworski Aug 22 '14 at 06:16

The Compiler compliance level is Version Dependent in eclipse. If you are using Eclipse 3.7 or lower then you won't get 1.7 compliance. Use Eclipse JUNO or higher.

For more on JDT Core 7 and its release related information

UPDATE:

Even eclipse 3.7.1 version supports Java 7 features and compliance level.
