Java读入优化

之前被软院校赛卡了一波T，很亏啊。以下抄袭自Codeforces的神仙Petr。

可能得系统研究Java怎么写了？缺点是不能使用hasNext()，可能需要在main()中解决。

import java.io.*;

import java.util.*;

public class Main {

	public static void main(String[] args) {

		InputStream inputStream = System.in;

		OutputStream outputStream = System.out;

		InputReader in = new InputReader(inputStream);

		PrintWriter out = new PrintWriter(outputStream);

		Solver solver = new Solver();

		solver.solve(in, out);

		out.close();

	}

	static class Solver {

		public void solve(InputReader in, PrintWriter out) {

		}

	}

	static class InputReader {

		public BufferedReader reader;

		public StringTokenizer tokenizer;

		public InputReader(InputStream stream) {

			reader = new BufferedReader(new InputStreamReader(stream), 32768);

			tokenizer = null;

		}

		public String next() {

			while (tokenizer == null || !tokenizer.hasMoreTokens()) {

				try {

					tokenizer = new StringTokenizer(reader.readLine());

				} catch (IOException e) {

					throw new RuntimeException(e);

				}

			}

			return tokenizer.nextToken();

		}

		public int nextInt() {

			return Integer.parseInt(next());

		}

		public long nextLong() {

			return Long.parseLong(next());

		}

	}

}
