Java Arrays Real-Life Examples

📦 Java Arrays – Real-Life Examples Arrays are widely used in Java to store collections of similar data. Here are some practical real-life examples of arrays. 1️⃣ Store Student Marks

public class Main {
public static void main(String[] args) {
int[] marks = {85, 90, 78, 92, 88}; // Marks of 5 studentsint sum = 0;
for (int mark : marks) {
sum += mark;
}

double average = sum / (double) marks.length;
System.out.println("Average marks: " + average);
}
}

public class Main {

public static void main(String[] args) {

int[] marks = {85, 90, 78, 92, 88}; // Marks of 5 studentsint sum = 0;

for (int mark : marks) {

sum += mark;

}

double average = sum / (double) marks.length;

System.out.println("Average marks: " + average);

}

Java For Loop Examples

Java For Loop Examples The for loop is commonly used when the number of iterations is known. Below are multiple practical examples. 📌 Example 1: Print 1 to 10

public class Main {
public static void main(String[] args) {
for (int i = 1; i <= 10; i++) {
System.out.println(i);
}
}
}

public class Main {

public static void main(String[] args) {

for (int i = 1; i <= 10; i++) {

System.out.println(i);

}

int i = 1;while (i <= 10) {
System.out.println(i);
i++;
}
}
}
