Learn Java by Example: Java Program to Find Largest Element of an Array

Java Program to Find Largest Element of an Array

In this program, you’ll learn to find the largest element in an array using a for loop in Java.


Example: Find the largest element in an array

public class Largest{

    public static void main(String[] args){
        double[] numArray = { 23.4, -34.5, 50.0, 33.5, 55.5, 43.7, 5.7, -66.5 };
        double largest = numArray[0];

        for (double num: numArray) {
            if(largest < num)
                largest = num;

        System.out.format("Largest element = %.2f", largest);


Largest element = 55.50

In the above program, we store the first element of the array in the variable largest.

Then, largest is used to compare other elements in the array. If any number is greater than largestlargest is assigned the number.

In this way, the largest number is stored in largest when it is printed.

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
