Ints max() function in Java

The max() method of the Ints class returns the greatest value present in array. Following is the syntax −

static int max(int... array)

Let us first see an example −

Example

import com.google.common.primitives.Ints;
class Demo {
   public static void main(String[] args) {
      int[] myArr = { 10, 20, 30, 40, 50, 60,20, 80, 20, 100 };
      System.out.println(Ints.join("-", myArr));
      System.out.println("Maximum value from the array = " + Ints.max(myArr));
      // finding last index of element 20
      int index = Ints.lastIndexOf(myArr, 20);
      if (index != -1) {
         System.out.println("The last index of element 20 = " + index);
      } else {
         System.out.println("The element 20 is not in the array.");
      }
   }
}

Output

Maximum value from the array = 100
10-20-30-40-50-60-20-80-20-100
The last index of element 20 = 8
