When finally block is NOT called?

Finally is the block of code that executes always. The code in finally block will execute even if an exception is occurred. Finally block is NOT called in following conditions

1.public class TryCatchFinally {
    public static void main(String ar[]){
        try{
               System.out.println("try block");
              }
        catch(Exception e){
                System.out.println("catch block");
                System.exit(0);
        }finally{
            int x=0;
            if(x>1){
            System.out.println("finally block");
            }
        }
    }
}
output:
try block

2. public class TryCatchFinally {
    public static void main(String ar[]){
        try{
           System.out.println("try block");     
           System.exit(0);
        }catch(Exception e){
                System.out.println("catch block");
                System.exit(0);
        }finally{          
            System.out.println("finally block");          
        }
    }
}
output:
try block
3. public class TryCatchFinally {
    public static void main(String ar[]){
        try{
            int x=0;
            if(x<1){
                    throw new Exception();
                }     
             
        }catch(Exception e){
                System.out.println("catch block");
                System.exit(0);
        }finally{
            int x=0;
            if(x>1){
            System.out.println("finally block");
            }
        }
    }
}
output:
catch block

4. public class TryCatchFinally {
    public static void main(String ar[]){
        try{
            int x=0;
            if(x<1){
            throw new Exception();
            }
        }catch(Exception e){
                System.out.println("catch block");
                System.exit(0);
        }finally{          
            System.out.println("finally block");          
        }
    }
}
output:
catch block
