在每个句子前面添加两个空格

Question

如果我有一个很长的文本字符串，我应该使用什么命令或方法才能在每行前面留下两个空格？ 假设

String sentences = "The car is blue. 
                    The sky is blue. 
                    The house is blue."

输出应为

  The car is blue.   
  The sky is blue.   
  The house is blue.


public static String indentByTwoSpaces(String text)
{
    String[] words = text.split(" ");
}

Answer 1

简单使用String.replace

System.out.println ("  " + str.replaceAll("(\r\n|\n)", "\r\n  "));

Answer 2

1。使用正则表达式拆分行。

2. 使用循环进行迭代，通过格式化来打印内容     提供的字符串

注意 - 如果你需要在开始时将字符串与两个空格连接起来，那么只需将字符串拆分并连接两个空格＆lt;“”+ ---＆gt;并返回

        String splittedLines[] = text.split("\\r?\\n");
        int index = 0;
        while(index != splittedLines.length) {
            String.format("  %s", splittedLines[index]);
            index++;
        }

这完全取决于您的输入。

见下文，这将打印出您想要的输出，因为输入在句点后没有空格。如果有，你可以相应调整。

public class TestMain {

public static void main(String[] args) {

   // notice how my text input doesnt have spaces after the periods
    String text = "The car is blue.The sky is blue.The house is blue.";

    StringBuilder sb = new StringBuilder();

    String splittedLines[] = text.split("\\.");
    int index = 0;
    while(index != splittedLines.length) {

        // if there are spaces after the periods, consider adjusting this
        sb.append("  ");

        sb.append(splittedLines[index]);
        sb.append("\n");
        index++;
    }

    System.out.print(sb);

}

}

根据您的要求，您需要相应地分割线来识别句子。然而，根据给定的样本集合，我会注意到每个句子结束后的句号是完整的。因此，我建议使用（。）与正则表达式相应地分割线。然后你可以相应地格式化你的线，如下所示。

public class AddingSpaces {

    public static void main(String[] args) {

       // As shown below, you can have your own sentence even with or without spaces
        String text = "The car is blue.The sky is blue.The house is blue.";

        // Since there are multiple sentences, you can split it from full-stop 
        String splittedLines[] = text.split("\\.");
        for (String line: splittedLines) {
            StringBuilder sb = new StringBuilder();
            sb.append("  ").append(line);
            //Print the lines accordingly
            System.out.println(sb);
        }
    }
}
