Switch statement does not accept a String variable
Can someone please tell me why the switch statement doesn't recognize the gat
String variable . IDE
tells me there primitive
is required
(int, char, short ....) but it found the string.
String gat = temp[i];
switch (gat) {
case "a":
output[i] = 12 * k;
break;
case "b":
output[i] = 23 * k;
break;
case "c":
output[i] = 34 * k;
break;
}

Your project's compliance level is set to Java 6 or earlier, you cannot use String
as case shortcuts before Java 7. But in case of your question, you can usecharAt(0)
String gat=temp[i];
switch (gat.charAt(0))
{
case 'a':
output[i] = 12 * k;
break;
case 'b':
output[i] = 23 * k;
break;
case 'c':
output[i] = 34 * k;
break;
}
