无法正确对齐输出

Question

1. 项目清单

    import java.io.BufferedReader; import java.io.File; import java.io.IOException; import java.io.InputStreamReader; public class test104 { public String[] b=new String[200]; public String flex(String ps) throws IOException { String result=""; File file=new File("C:\\\\ProgramData"); ProcessBuilder pb = new ProcessBuilder("cmd","/C",ps); pb.directory(file); Process p = pb.start(); BufferedReader reader = new BufferedReader(new InputStreamReader( p.getInputStream())); String readline; //result=reader.readLine(); int i=0; result=reader.readLine(); StringBuilder sb = new StringBuilder(); while ((readline = reader.readLine()) != null) { sb.append(readline); System.out.println(readline); b[i]=readline; i++; System.out.println("<br>"); } try { int exitValue = p.waitFor(); } catch (InterruptedException e) { e.printStackTrace(); } finally{ //out.close(); } return sb.toString(); }} Print.jsp </head> <%@ page import="com.test104" %> <body> <% com.test104 f1=new test104(); int j=0; String k=f1.flex("dir"); String readline; out.println(k); %> 

输出未直线对齐。 它应该像一个在另一个下面一样！

这是jsp页面中的输出。

Answer 1

遵循以下代码

 StringBuilder sb = new StringBuilder();
 while ((readline = reader.readLine()) != null) {
     sb.append(readline);
 }
 someOutputMethod( sb.toString() );

将从阅读器读取的输入中删除所有行尾。 您必须在每行之后或在您认为必要时在每行末尾附加'\\n' 。
