Thread: Creating an object with a String from file IO

Hi folks,

I have a chemicals class with various instance variables such as chemical name, boiling point, freeze point etc.

I have created a stream input file with a .csv extension where I want the user to specify a process stream (flow rate, temperature, chemicals inside the stream etc.).

I have the following code in the main method:

Chemicals [] chemObject = new Chemicals[2]; //2 chemicals per stream
//If i add this line next: System.out.println(inputStream.next()); it prints the name of the chemical I want
chemObject[0] = new Chemicals(inputStream.next());
System.out.println(chemObject[0].getName()); //this prints out null meaning that the chemObject[0] did not get created?

I realized I should have provided more info on the actual Chemicals class and its constructors:

 public Chemicals(String name) //Overloaded consutrctor
  {
    if (name  == "toluene")
    {
      this.name = "toluene";
      this.boilingPoint=110.6;
    }
  }
public String getName()
  {
    return this.name; 
  }

How do I create an object with a string from an input stream?

Cheers

thanks Norm.

It was indeed a problem with the Strings being compared and not with my input streams.
