Java Exercises: Find the largest element between first, last, and middle values from an array of integers

Java Basic: Exercise-82 with Solution

Write a Java program to find the largest element between first, last, and middle values from an array of integers (even length).

Sample Solution:

Java Code:

import java.util.Arrays; 
 public class Exercise82 {
 public static void main(String[] args)
 {
    int[] array_nums = {20, 30, 40, 50, 67};
	System.out.println("Original Array: "+Arrays.toString(array_nums)); 
	int max_val = array_nums[0];
	if(max_val <= array_nums[array_nums.length-1])
		max_val = array_nums[array_nums.length-1];
	if(max_val <= array_nums[array_nums.length/2])
		max_val = array_nums[array_nums.length/2];
	System.out.println("Largest element between first, last, and middle values: "+max_val);  
 }
}

Sample Output:

Original Array: [20, 30, 40, 50, 67]                                   
Largest element between first, last, and middle values: 67

Java: Tips of the Day

countOccurrences

Counts the occurrences of a value in an array.

Use Arrays.stream().filter().count() to count total number of values that equals the specified value.

public static long countOccurrences(int[] numbers, int value) {
    return Arrays.stream(numbers)
            .filter(number -> number == value)
            .count();
}
