I'm trying to use a switch statement in a Android Application. This switch statement is testing the value of a String, and then based of that changing the value of another String.
String s1 = "a" then String s2 = "1"
I keep getting an error that says I need to change the compliance to 1.7. After I do that, I then get an error that says I need to change the compliance to 1.6.
Is there a way to fix this? or can anyone think of a work around for this?
Java does not support String in switch/case earlier java 7. But if you use java 6 you can achieve the desired result by using an enum.
private enum Fruit {
apple, carrot, mango, orange;
}
String value; // assume input
Fruit fruit = Fruit.valueOf(value); // surround with try/catch
switch(fruit) {
case apple:
method1;
break;
case carrot:
method2;
break;
// etc...
}
public static final fields.
char itself?Using String comparison with equals() instead of switch on Strings (which is available in Java 7) could look like this:
//as an example, if s2 equals 'b'
String s2 = "b";
//this uses String's equals() method
if (s1.equals("a")) then {
s2 = "1";
}
else if (s1.equals("b")) then {
s2 = "2";
}
else {
s2 = "3";
}
Of course, adapt the conditions to your needs.
donot use switch case but rather use if-else with string equals() method. it will help in code compatibility as switch with strings is only available with jdk 1.7+.
You will need to add the below code in your pom.xml if in case it is a maven project.
<properties>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.source>1.8</maven.compiler.source>
</properties>
