🚀 Programming Example
Searching in an Array in java
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
import java.util.Arrays;
public class SearchArray {
public static void main(String[] args) {
int[] arr = {10, 20, 30, 40, 50};
int key = 30;
int index = Arrays.binarySearch(arr, key); // array must be sorted
if(index >= 0){
System.out.println("Element found at index: " + index);
} else {
System.out.println("Element not found");
}
}
}
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
