Complete the following Java method that returns the maximum

Complete the following Java method that returns the maximum element of an array:

public class Exercise2{

public static void main(String[] args) {

Integer[] numbers = {1, 2, 3};

System.out.println(max(numbers));

String[] words = {\"red\", \"green\", \"blue\"};

System.out.println(max(words));

Circle[] circles = {new Circle(3), new Circle(2.9), new Circle(5.9)};

System.out.println(max(circles));

}

static class Circle implements Comparable<Circle> {

double radius;

public Circle(double radius) {

this.radius = radius;

}

@Override

public int compareTo(Circle c) {

if (radius < c.radius)

return -1;

else if (radius == c.radius)

return 0;

else

return 1;

}

@Override

public String toString() {

return \"Circle radius: \" + radius;

}

}

public static <E extends Comparable<E>> E max(E[] list) {

// Your code here!

}

}

Solution

HI Friend, Please find my implementation.

Please let me know in case of any issue.

public class Exercise2{

   public static void main(String[] args) {

       Integer[] numbers = {1, 2, 3};

       System.out.println(max(numbers));

       String[] words = {\"red\", \"green\", \"blue\"};

       System.out.println(max(words));

       Circle[] circles = {new Circle(3), new Circle(2.9), new Circle(5.9)};

       System.out.println(max(circles));

   }

   static class Circle implements Comparable<Circle> {

       double radius;

       public Circle(double radius) {

           this.radius = radius;

       }

       @Override

       public int compareTo(Circle c) {

           if (radius < c.radius)

               return -1;

           else if (radius == c.radius)

               return 0;

           else

               return 1;

       }

       @Override

       public String toString() {

           return \"Circle radius: \" + radius;

       }

   }

   public static <E extends Comparable<E>> E max(E[] list) {

      

       if(list == null)

           return null;

      

       E max = list[0]; // initializing with first element

      

       for(int i=1; i<list.length; i++){

          

           if(max.compareTo(list[i]) < 0) // if current element from list is greater than max

               max = list[i];

       }

      

       return max;

   }

}
