Question

使用java guava spliter分割时可能不会破坏单词吗？

我有这个样本：

var String msg = "My name is Fabio and I have a dog";

Splitter.fixedLength(5).split(msg).forEach(item -> {
            System.out.println(item);
        });

这将打印：

My na

me is

 Fabi

o and

 I ha

ve a 

dog

但我希望他不要说我的话

就像这样：

My naME

is Fabio

and I have

a dog

我没有控制文本，我只想保留最后一个词为everty split

fixedLength(5)

这种逻辑应该回答你的问题。

Answer 2

您可以在迭代时拆分单词并构建行：

final List<String> lines = new ArrayList<>();
final StringBuilder builder = new StringBuilder();
for (String word : Splitter.on(' ').split(msg)) {
    if (builder.length() == 0) {
        builder.append(word);
    } else if (builder.length() <= 5) {
        builder.append(' ').append(word);
    } else {
        lines.add(builder.toString());
        builder.setLength(0);
        builder.append(word);
    }
}
if (builder.length() > 0) {
    lines.add(builder.toString());
}
lines.forEach(System.out::println);

输出：

My name
is Fabio
and I have
a dog
