SATRLARNI O’ZGARTIRISH.

String sinfining to String metodi yoki shaxsiy realizasiyasi mavjud.

class Point {

int х, у;

Point(int x, int у) {

this.x = х;

this.у = у;

}

public String toString() {

return "Point[" + x + ", " + у + "]";

} }

class toStringDemo {

public static void main(String args[]) {

44
Point p = new Point(10, 20);

Console.write ("p = " + p);

} }

Misoldan olingan natija:

p = Point[10, 20]

TENGLASHTIRISH.

Agar ikki satrning bir xilligini bilmoqchi bo’lsangiz unda siz String sinfining equals metodidan foydalanishingiz mumkin.Bu metodning alternative formasi equalsIgnoreCase deb nomlanadi.

Keyingi misolda ikki metodning qo’llanilishi illyustrasiyasi keltirilgan. class equalDemo {

public static void main(String args[]) {

String s1 = "Hello";

String s2 = "Hello";

String s3 = "Good-bye";

String s4 = "HELLO";

Console.Write(s1 + " equals " + s2 + " -> " + s1.equals(s2));

Console.Write (s1 + " equals " + s3 + " -> " + s1.equals(s3));

Console.Write (s1 + " equals " + s4 + " -> " + s1.equals(s4));

Console.Write (s1 + " equalsIgnoreCase " + s4 + " -> " +

s1.equalsIgnoreCase(s4));

} }

Natija:

Hello equals Hello -> true

Hello equals Good-bye -> false

Hello equals HELLO -> false

Hello equalsIgnoreCase HELLO -> true
