Java如何将字符串中的每个单词大写?
此示例说明如何大写字符串。我们使用WordUtilsApache提供的类中的方法commons-text;。我们可以使用WordUtils.capitalize(str)或WordUtils.capitalizeFully(str)。
让我们看下面的例子:
package org.nhooo.example.commons.text;
import org.apache.commons.text.WordUtils;
public class WordCapitalize {
public static void main(String[] args) {
//将字符串中所有用空格分隔的单词大写,
//每个单词只有第一个字母大写。
String str = WordUtils.capitalize(
"The quick brown fox JUMPS OVER the lazy dog.");
System.out.println("str = " + str);
//将字符串中所有由空格分隔的单词大写
//其余字符串为小写。
str = WordUtils.capitalizeFully(
"The quick brown fox JUMPS OVER the lazy dog.");
System.out.println("str = " + str);
}
}这是程序的结果:
str = The Quick Brown Fox JUMPS OVER The Lazy Dog. str = The Quick Brown Fox Jumps Over The Lazy Dog.
