Am I allowed to have a switch
statement which decides what to return? For example, I want to return something different based on what my random generator come up with. Eclipse is giving me an error wanting me to put the return
statement outside the switch
.
My code:
public String wordBank() { //Error here saying: "This method must return a type of string"
String[] wordsShapes = new String[10];
wordsShapes[1] = "square";
wordsShapes[2] = "circle";
wordsShapes[3] = "cone";
wordsShapes[4] = "prisim";
wordsShapes[5] = "cube";
wordsShapes[6] = "cylinder";
wordsShapes[7] = "triangle";
wordsShapes[8] = "star";
wordsShapes[9] = "moon";
wordsShapes[10] = "paralellogram";
Random rand = new Random();
int i = rand.nextInt(11);
if (i == 0) {
i = rand.nextInt(11);
}
switch (i) {
case 1:
return wordsShapes[1].toString();
case 2:
return wordsShapes[2].toString();
case 3:
return wordsShapes[3].toString();
case 4:
return wordsShapes[4].toString();
case 5:
return wordsShapes[5].toString();
case 6:
return wordsShapes[6].toString();
case 7:
return wordsShapes[7].toString();
case 8:
return wordsShapes[8].toString();
case 9:
return wordsShapes[9].toString();
case 10:
return wordsShapes[10].toString();
}
}
Sorry, but in that case, why not just simply do:
return wordsShapes[i].toString();
This way you can avoid the switch and all.
Hope that helps,
