Hayotiy misol

Massivlardan foydalanishning amaliy misolini ko‘rsatish uchun turli yoshlarning o‘rtacha qiymatini hisoblaydigan dastur yaratamiz:

// An array storing different ages
int ages[] = {20, 22, 18, 35, 48, 26, 87, 70};

float avg, sum = 0;

// Get the length of the array
int length = ages.length;

// Loop through the elements of the array
for (int age : ages) {
  sum += age;
}

// Calculate the average by dividing the sum by the length
avg = sum / length;

// Print the average
System.out.println("The average age is: " + avg);

Bu misolda esa turli yoshlar orasidan eng kichigini topadigan dastur yaratamiz:

// An array storing different ages
int ages[] = {20, 22, 18, 35, 48, 26, 87, 70};

// Get the length of the array
int length = ages.length;

// Create a 'lowest age' variable and assign the first array element of ages to it
int lowestAge = ages[0];

// Loop through the elements of the ages array to find the lowest age
for (int age : ages) {
  // Check if the current age is smaller than the current 'lowest age'
  if (lowestAge > age) {
    // If the smaller age is found, update 'lowest age' with that element
    lowestAge = age;
  }
}

// Output the value of the lowest age
System.out.println("The lowest age in the array is: " + lowestAge);

Sonlar ro‘yxati bilan ishlaydigan dastur yarating: manfiy qiymatlarni o‘tkazib yuboring, lekin nol uchrasa, butunlay to‘xtang:

int[] numbers = {3, -1, 7, 0, 9};

for (int n : numbers) {
  if (n < 0) {
    continue; // skip negative numbers
  }
  if (n == 0) {
    break; // stop loop when zero is found
  }
  System.out.println(n);
}

Massivdagi eng katta va eng kichik qiymatlarni aniqlab boradigan dastur yarating:

int[] numbers = {45, 12, 98, 33, 27};

int max = numbers[0];
int min = numbers[0];

for (int n : numbers) {
  if (n > max) {
    max = n;
  }
  if (n < min) {
    min = n;
  }
}

System.out.println("Max: " + max);
System.out.println("Min: " + min);

Teatr qatoridagi o‘rindiq raqamlarini chiqaradigan dastur yarating: unda o‘rindiq raqami (indeks) ham, u yerda kim o‘tirgani (qiymat) ham ko‘rsatilsin:

String[] seats = {"Jenny", "Liam", "Angie", "Bo"};

for (int i = 0; i < seats.length; i++) {
  System.out.println("Seat number " + i + " is taken by " + seats[i]);
}
