简单的行替换不能在Java中工作

Question

我在名为 Sample.txt

的文本文件中提供了以下内容

This is line1
This is line2

这里我想用和替换这个新行，我的意思是输出应该像

This is line1 and This is line2

我的代码如下。

BufferedReader br = null;

try {

    String sCurrentLine;

    br = new BufferedReader(new FileReader("C:\\Users\\home\\Desktop\\Test\\Sample.txt"));
    int i = 0;
    while ((sCurrentLine = br.readLine()) != null) {

        String sCurrentLine1 = sCurrentLine.replaceAll("\\n+", "0NL0");
        System.out.println("Line No." + i + " " + sCurrentLine1);
        i++;
    }

当我打印这个时，我得到输出

Line No.0 This is line1
Line No.1 This is line2

请让我知道如何更换这条新线。

您不需要执行BufferedReader::readLine() \n方法会从sCurrentLine中返回的字符串中删除try { String sCurrentLine; StringBuilder sb = new StringBuilder();// Declare a string builder object. br = new BufferedReader(new FileReader("C:\\Users\\home\\Desktop\\Test\\Sample.txt")); int i = 0; while ((sCurrentLine = br.readLine()) != null) { if(i>0) { sb.append(" and "); } sb.append(sCurrentLine); System.out.println("Line No." + i + " " + sCurrentLine); i++; } System.out.println("Appended output " + sb.toString()); 个字符。所以你要做的就是追加返回的行。

示例：

              swal({
                        html: true,
                        title: "Message",
                        text: 'Hello World',
                        type: "success",
                    }, function () {
                        // steps if success.
                    });
