The following method should return the text variable three times, combined together side by side. What should the return statement say? static String echostring(String text) \{ return text text text Nothing should be added. text + text + text text + "ln" + text + "ln" + text Which of the following is a wrapper class and would work with a generic method? boolean long Float char In the update to the tic-tac-toe game that introduced loops, why are the variables col and row set to 0 after each for loop? For improved readability The code won't compile without them there. It ensures the validation loop will run correctly on the next turn. They could be initialized to any value at all. Given the following methods: public static int addNumPlusMore(int num1, int num2) \{ return num1 + num2 +5; \} public static int addNumplusMore(int num1, int num2, int num3) \{ return num1 + num2 + num 3+10; ? What would val be set to after the following statement: intval=addNumPlusMore(5,10); 25
