# Switch-Case

Операторът Switch-Case се използва, когато имаме няколко опции (или възможности за избор) и може да се наложи да изпълним различна задача за всеки избор.

```
switch (variable or an integer expression)
{
     case constant:
     //Java code
     ;
     case constant:
     //Java code
     ;
     default:
     //Java code
     ;
}
```

Пример:

```
public class SwitchCaseExample1 {

public static void main(String[] args) {
     int num=2;
     switch(num+2)
     {
        case 1:
	  System.out.println("Case1: Value is: "+num);
	case 2:
	  System.out.println("Case2: Value is: "+num);
	case 3:
	  System.out.println("Case3: Value is: "+num);
        default:
	  System.out.println("Default: Value is: "+num);
      }
   }
}
```

Оператора break не е задължителен, прекратява изпълнението след избор

### Пример без break:

```
public class SwitchCaseExample2 {

public static void main(String[] args){
      int i=2;
      switch(i)
      {
	 case 1:
	   System.out.println("Case1 ");
	 case 2:
	   System.out.println("Case2 ");
	 case 3:
	   System.out.println("Case3 ");
	 case 4:
           System.out.println("Case4 ");
	 default:
	   System.out.println("Default ");
      }
   }
}
```

**Изход:**

```
Case2 
Case3 
Case4 
Default 
```

### Пример с break

```
public class SwitchCaseExample2 {

public static void main(String[] args){
      int i=2;
      switch(i)
      {
	 case 1:
	   System.out.println("Case1 ");
	   break;
	 case 2:
	   System.out.println("Case2 ");
	   break;
	 case 3:
	   System.out.println("Case3 ");
	   break;
	 case 4:
           System.out.println("Case4 ");
           break;
	 default:
	   System.out.println("Default ");
      }
   }
}
```

**Output:**

```
Case2
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://programmingfundamental.gitbook.io/programmingwithjava/obektno-orientirano-programirane-1-chast/laboratorno-uprazhnenie-1/switch-case.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
