如何才能正确提交各位大侠,小弟第一次来做这里做题目,不知道我这样做是否正确,ID3650这个题,我在自己机器上跑没问题了,一提交上服务器就报不少错误,比如:Main.java:9: class PercentSolution is public, should be declared in a file named PercentSolution.java public class PercentSolution { ^ 1 error (我觉得奇怪,我只是传源码,文件又不要我建立,为什么出现这种错误) 我的源码如下: import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; public class PercentSolution { public static void main(String[] args) { BufferedReader br = new BufferedReader(new InputStreamReader(System.in));//接收控制台输入 StringBuilder sb = new StringBuilder(); int temp, num = 0; List<String> list = new ArrayList<String>(); try { while ((temp = br.read()) != -1) { sb.append((char) temp); if (temp == '#') {//字符#作为输入结束标志 break; } } for (int j = 0; j < sb.length(); j++) { if (((int) sb.toString().charAt(0)) == 32 || ((int) sb.toString().charAt(sb.length() - 2)) == 32) {//首字符和最末一个字符不能为空格 num = 2; break; } if (sb.toString().charAt(j) != '#') { list.add(j, String.valueOf(sb.toString().charAt(j)));//将字符作为String存入list中,这样做方便下面处理 } if (j <= sb.length() - 3) { if ((int) sb.toString().charAt(j) == 32 && (int) sb.toString().charAt(j + 1) == 32) {//不能有连续两个空格 num = 1; break; } } } sb.delete(0, sb.length()); br.close(); } catch (IOException e) { e.printStackTrace(); } if (num == 0) {//通过上面的判断,符合题目条件,进行处理 for (int i = 0; i < list.size(); i++) { if (list.get(i).equals(" ")) {//开始处理,如果输入中有空格字符,则替换为“20%”,以下类推 list.set(i, "%20"); } else if (list.get(i).equals("!")) { list.set(i, "%21"); } else if (list.get(i).equals("$")) { list.set(i, "%24"); } else if (list.get(i).equals("%")) { list.set(i, "%25"); } else if (list.get(i).equals("(")) { list.set(i, "%28"); } else if (list.get(i).equals(")")) { list.set(i, "%29"); } else if (list.get(i).equals("*")) { list.set(i, "%2a"); } } for (int j = 0; j < list.size(); j++) { sb.append(list.get(j));//将处理过的list中的内容,复制加到sb中,为了符合题目的输出要求 } } if (sb.toString().length() > 0) System.out.println(sb.toString()); } } Followed by:
