Problem: Write a Java program to find the largest element in an array.
Solution Approach:
- Understand the Problem: Need to scan through an array and determine the maximum value.
- Breakdown: Initialize a variable with the first element, iterate through remaining elements, and update the variable when a larger element is found.
- Algorithm:
- Set max = first element
- For each element in the array:
- If element > max, update max
- Output max
- Code Implementation:
```java
public class LargestElement {
public static void main(String[] args) {
int[] nums = {23, 45, 67, 89, 12, 34};
int max = nums[0];
for (int i = 1; i < nums.length; i++) {
if (nums[i] > max) {
max = nums[i];
}
}
System.out.println("Largest element is: " + max);
}
