Javada ma’lumot turlari (data types)
Javada ma’lumotlar turlari 2 ta
1. Soda(primitive )
2. Soda bo’lmagan (non primitive)

Java dasturlash tilida eng ko’p ishlatilardigan operatorlar (solishtirish operatorlari, mantiqiy operatorlar, o‘zlashtirish operatori)

Solishtirish operatori
Ikki operatorni bir-biri bilan solishtirishda ishlatialdi. Odatda, solishtirish operatorlar, shart berish operatori(if) va sikl(while for) ammalari bilan ishlatialdi.
Bu aperatrlar ikki xil natija qaytarishi mumkin true yokiy false
Java dasturlash tilida quyidagi solishtirish operatorlari mavjud:
== -> teng
!= -> teng emas
> -> katta
< -> kichik
>= -> katta yokiy teng
<= -> kichik yokiy teng

public static void main(String[] args) {
int a = 3;
int b = 6;
