2.Write a Java switch statement that checks a variable of type String called myString, and increments (adds one to) an int variable named numberStates if the variable has the value “Colorado” or “Utah”, and increments an int variable named numberCities if the variable has the value “Denver” or “Fort Collins”, and prints “Not recognized” if the string is anything else. Assume all variables are previously declared.
switch(myString){
case 'Colorado' : numberStates++;
break;
case 'Utah' : numberStates++;
break;
case 'Denver' : numberCities++;
break;
case 'Fort Collins' : numberCities++;
break;
default : System.out.println("Not recognived")
} I got 4/5 pts for this. What is wrong here?
Explanation / Answer
Answer 1: Answer is D class can contain the methods and data
Answer 2: here the mistake is case labels in '' so as these are strings we need put them in " "
switch(myString){
case "Colorado" : numberStates++;
break;
case "Utah" : numberStates++;
break;
case "Denver" : numberCities++;
break;
case "Fort Collins" : numberCities++;
break;
default : System.out.println("Not recognived");
}
