尝试给出编译错误的块

Question

I am trying to use try block for my code, but it gives compilation error. Code is :

    public static void main(String[] args) 
    {
        try 
        { 
             //my logic goes here
            return; 
        } 
    }

Please help solving problem.

Answer 1

try block can not be used without catch/finally block.

your code should be like :

    public static void main(String[] args) 
    {
        try 
        { 
            //mu logic goes here
            return; 
        }
        catch (Exception e)
        {

        }    
    }

or

    public static void main(String[] args) 
    {
        try 
        { 
                //mu logic goes here
            return; 
        }
        finally
        {

        }
    }

or it can have both multiple catch but only one finally in any combinations.

refer to java docs for basic learning of try-catch

Answer 2

Most basic correct form. This will catch any error and print out the error message.

public static void main(String[] args) 
    {
        try 
        { 
         //my logic goes here

        }
        catch(Exception e){
             System.out.println(e);
        }
}

Answer 3

catch with try or finally is mandatory, please refer to below code

public static void main(String[] args) 
{
    try 
    { 
         //my logic goes here
        return; 
    } catch(Exception e){
      // Do Something
    }
}


  public static void main(String[] args) 
{
    try 
    { 
         //my logic goes here
        return; 
    } finally{
      // Do Something
    }
}
