Rotate user input string to uppercase Java

Question

This may seem like a silly question, but after going through google pages, I havnt been able to find the answer I want.

s1.setName(JOptionPane.showInputDialog("Enter Name: "); 

For the above snippet of code fo, how would I format the data that the user entered to be all capitals?

Any help here would be appreciated.

Answer 1

The String class has a toUpperCase () method on it.

JOptionPane.showInputDialog (..) returns a string, so you can use:

 JOptionPane.showInputDialog("Enter name: ").toUpperCase(); 

Answer 2

See String.toUpperCase ()

Remember that String is immutable, so this creates a repeating string
