Java metodlarni qayta yuklash

Metodlarni qayta yuklash (overloading)

Metodlarni qayta yuklash (method overloading) yordamida bir nechta metod bir xil nomga, lekin turli parametrlarga ega bo‘lishi mumkin:

Misol

int myMethod(int x)
float myMethod(float x)
double myMethod(double x, double y)

Quyidagi misolni ko‘rib chiqing: unda turli tipdagi sonlarni qo‘shadigan ikkita metod bor:

Misol

static int plusMethodInt(int x, int y) {
  return x + y;
}

static double plusMethodDouble(double x, double y) {
  return x + y;
}

public static void main(String[] args) {
  int myNum1 = plusMethodInt(8, 5);
  double myNum2 = plusMethodDouble(4.3, 6.26);
  System.out.println("int: " + myNum1);
  System.out.println("double: " + myNum2);
}

Bir xil ishni bajarishi kerak bo‘lgan ikkita metodni aniqlash o‘rniga, bitta metodni qayta yuklagan (overload) ma’qul.

Quyidagi misolda plusMethod metodini ham int, ham double uchun ishlaydigan qilib qayta yuklaymiz:

Misol

static int plusMethod(int x, int y) {
  return x + y;
}

static double plusMethod(double x, double y) {
  return x + y;
}

public static void main(String[] args) {
  int myNum1 = plusMethod(8, 5);
  double myNum2 = plusMethod(4.3, 6.26);
  System.out.println("int: " + myNum1);
  System.out.println("double: " + myNum2);
}

Eslatma: Parametrlar soni va/yoki tipi har xil bo‘lsa, bir nechta metod bir xil nomga ega bo‘lishi mumkin.
