Java program to find the largest element in an array

Comprehensive List of Java Examples

In this program, you will learn how to use the for loop in Java to find the largest element in an array.

Example: Find the maximum element in the 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("Maximum Element = %.2f", largest);
　　　　}
}

When running the program, the output is:

Maximum 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 largest, a new number is assigned to largest.

Thus, the data of the maximum element will be stored in largest.
