convert whole to java string

Question

How do I convert the Integer to String type in Java?

The variable matricula is declared as whole, but to show it on the screen it asks to convert it to String.

txtmatricula.setText(txtmat.getMatricula()));

Answer 1

Use String.valueOf()

String matriculaString = String.valueOf(txtmat.getMatricula())
txtmatricula.setText(matriculaString);

Perks

• Also for the types: Double, Float or Long;
• It has the purpose of being used in conversions, so many classes have this method, such as: String, Integer, Double, Bigdecimal, etc.
• In the case of Integer, the valueOf() cacheia numbers frenquently used from -127 to 128;
• Delegate the conversion of String to the respective class method, in the case of Integer, delegate to Integer.toString(), which leaves the number representation in String, consistent;
