首先,我们需要创建一个Java类,命名为RemoveNewLineExample。在这个类中,我们定义了一个静态方法removeNewLine来处理字符串中的换行符: publicclassRemoveNewLineExample{publicstaticStringremoveNewLine(Stringinput){// 使用正则表达式替换换行符为空字符串Stringoutput=input.replaceAll("(\\r\\n|\\n|\\r)","");...
publicclassStringRemoveNewLine{publicstaticvoidmain(String[]args){// 创建一个字符串变量并赋值Stringstr="Hello World\n";// 使用trim()方法去除字符串两端的空格StringtrimmedStr=str.trim();// 判断字符串最后一个字符是否为换行符if(trimmedStr.endsWith("\n")){// 如果是换行符,则使用substring()方法...
io.IOException; public class RemoveLineNumbers { public static void main(String[] args) { String inputFile = "input.txt"; // 原始文本文件路径 String outputFile = "output.txt"; // 删除行号后的文本文件路径 try { BufferedReader reader = new BufferedReader(new FileReader(inputFile)); ...
io.IOException; public class RemoveLineNumbers { public static void main(String[] args) { String inputFile = "input.txt"; // 原始文本文件路径 String outputFile = "output.txt"; // 删除行号后的文本文件路径 try { BufferedReader reader = new BufferedReader(new FileReader(inputFile)); ...
Note:In programming, whitespace is any character or series of characters that represent horizontal or vertical space. For example: space, newline\n, tab\t, vertical tab\vetc. Example: Java String trim() classMain{publicstaticvoidmain(String[] args){ ...
