find max in java code example

Example 1: java max

public class Test { 

   public static void main(String args[]) {
      System.out.println(Math.max(12.123, 12.456));      
      System.out.println(Math.max(23.12, 23.0));  
   }
}

Example 2: max_value in java

(stores the maximum possible value for any integer variable)
    public static void main(String[] arg)
    {
  		System.out.println("Integer.MAX_VALUE = "
                           + Integer.MAX_VALUE);///output :-2147483647
    }
}
Any integer variable cannot store any value beyond this limit

Example 3: find max in java

int[] arr = {2, 3, 4, 5, 6, 7, 8, 9,};
        int max = arr[0]; // max tanimliyorsun
        int min = arr[0];  // min tanimliyorsun

        for (int i = 0; i < arr.length; i++) {
            if (arr[i] > max){ 
// array's index are compared with each other,
// whichever is greater will be assigned to max
                max = arr[i];
            }
            if(arr[i] < min){ 
//array's index are compared with each other,
// whichever is smaller will be assigned to min
                min = arr[i];
            }
        }
        System.out.println(max); // 9
        System.out.println(min);  // 2
