本文介绍了将句子中的第一个单词用多个句子大写的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
例如:
字符串s =这是a.line是.over
String s="this is a.line is .over "
应该来out as as
should come out as
这是a.Line is.Over
"This is a.Line is.Over"
我想过两次使用字符串标记符
I thought of using string tokenizer twice
-first split using"."
-second split using " " to get the first word
-then change charAt[0].toUpper
现在我不确定如何使用字符串标记生成器的输出作为另一个的输入?
now i'm not sure how to use the output of string tokenizer as input for another?
我可以使用split方法生成我试过的数组
also i can using the split method to generate array something i tried
String a="this is.a good boy";
String [] dot=a.split("\\.");
while(i<dot.length)
{
String [] sp=dot[i].split(" ");
sp[0].charAt(0).toUpperCase();// what to do with this part?
推荐答案
使用StringBuilder,无需拆分并创建其他字符串,依此类推,请参阅代码
Use StringBuilder, no need to split and create other strings, and so on, see the code
public static void main(String... args) {
String text = "this is a.line is. over";
int pos = 0;
boolean capitalize = true;
StringBuilder sb = new StringBuilder(text);
while (pos < sb.length()) {
if (sb.charAt(pos) == '.') {
capitalize = true;
} else if (capitalize && !Character.isWhitespace(sb.charAt(pos))) {
sb.setCharAt(pos, Character.toUpperCase(sb.charAt(pos)));
capitalize = false;
}
pos++;
}
System.out.println(sb.toString());
}
