将用户输入字符串转换为大写Java [英] Turn a User Input String to Upper Case Java

问题描述

这似乎是一个愚蠢的问题，但是经过google页面之后，我无法找到我想要的答案.

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

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

对于上面的fo代码，我将如何格式化用户输入的全部为大写字母的数据?

For the above piece fo code, how would i format the data the user entered to be all capitals?

这里的任何帮助将不胜感激.

Any help here would be appreciated.

推荐答案

String类具有toUpperCase()方法.

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

JOptionPane.showInputDialog(..)返回一个字符串，因此您可以使用:

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

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