Create a Math class that has the following methods:

public int divide(int x, int y) // returns x divided by y; returns ERROR if y is 0

public int max(int x, int y) // returns the bigger number: x or y

public int remainder(int x, int y) // returns the remainder when x is divided by y

public int triple(int x) // returns x times three

//returns true if the operation is any of \"*\", \"/\", \"%\", \"+\", or \"-\"; otherwise false:
public boolean isValidOperation(String operation) // use a switch statement  

Solution

Math.java

public class Math {
   public int divide(int x, int y) // returns x divided by y; returns ERROR if y is 0
   {
       if(y==0) return 0;
       else
           return x/y;
   }
   public int max(int x, int y) // returns the bigger number: x or y
   {
       if(x > y)
           return x;
       else
           return y;
   }
   public int remainder(int x, int y) // returns the remainder when x is divided by y
   {
       return x % y;
   }
   public int triple(int x) // returns x times three
   {
       int value = 0;
       for(int i =0; i<x; i++){
           value = value + x;
       }
       return value;
   }
   //returns true if the operation is any of \"*\", \"/\", \"%\", \"+\", or \"-\"; otherwise false:
   public boolean isValidOperation(String operation) // use a switch statement

       switch(operation.charAt(0)){
       case \'*\':

       case \'%\':
       case \'+\':
       case \'-\': status = true;break;
