Guava’s Ints.max() returns the greatest value present in array.
Syntax:
public static int max(int... array)
Parameters: This method takes the array as parameter which is a nonempty array of int values.
Return Value: This method returns the value present in array that is greater than or equal to every other value in the array.
Exceptions: The method throws IllegalArgumentException if array is empty.
Below examples illustrates the Ints.max() method:
Example 1:
// Java code to show implementation of // Guava's Ints.max() method import com.google.common.primitives.Ints;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
// Creating an integer array
int [] arr = { 2 , 4 , 6 , 10 , 0 , - 5 , 15 , 7 };
// Using Ints.max() method to get the
// maximum value present in the array
System.out.println( "Maximum value is: "
+ Ints.max(arr));
}
} |
Output:
Maximum value is: 15
Example 2: To demonstrate IllegalArgumentException
// Java code to show implementation of // Guava's Ints.max() method import com.google.common.primitives.Ints;
import java.util.Arrays;
class GFG {
// Driver's code
public static void main(String[] args)
{
try {
// Creating an integer array
int [] arr = {};
// Using Ints.max() method to get the
// maximum value present in the array
// This should raise "IllegalArgumentException"
// as the array is empty
System.out.println( "Maximum value is: "
+ Ints.max(arr));
}
catch (Exception e) {
System.out.println( "Exception: " + e);
}
}
} |
Output:
Exception: java.lang.IllegalArgumentException
