5 – Mavzu : Java dasturlash tilida Switch tanlash operatorlari

public static void main(String[] args) {

int xaridorningYoshi=17;

if(age < 18){

Sytem.out.print("Tamaki mahsuloti sotilmasin");

}

}

}

Ekranda:
Tamaki mahsulot sotilmasin
int xar idorningYoshi=17; -> kiruvchi qiymat
if(age < 18 ) -> tekshiruv jarayoni
Java IF-else operatori ta’rifi
Shart tekshirish jarayonida shart true bo’lsa, if blokdagi amal bajariladi, aks holda else block dagi amal bajariladi

1. 
   if(condition){
   
2. 
   //code if condition is true
   
3. 
   }else{
   
4. 
   //code if condition is false
   
5. 
   }
   

Misol: Berilgan sonni toq yoki toq emasligini bilish dasturi

1. 
   publicclass IfElseExample {
   
2. 
   publicstatic void main(String[] args) {
   
3. 
   int number=13;
   
4. 
   if(number%2==0){
   
5. 
   out.println("juft son");
   
6. 
   }else{
   
7. 
   out.println("toq son");
   
8. 
   }
   
9. 
   }
   
10. 
    }

Toq son
Java IF-else-if tanlash operatori
O’zbekcha qilib aytganda unisi bo’lmasa bunisi, bunisi bo’lmasa keyingisi degan ma’noda. if-else-if ketma ketligi shartlar ko’p bo’lgan hollarda ishlatiladi.

1. 
   if(condition1){
   
2. 
   //code to be executed if condition1 is true
   
3. 
   } else if(condition2){
   
4. 
   //code to be executed if condition2 is true
   
5. 
   } else if(condition3){
   
6. 
   //code to be executed if condition3 is true
   
7. 
   }
   
8. 
   ...
   
9. 
   else {
   
10. 
    //code to be executed if all the conditions are false
    
11. 
    }
