这篇文章主要介绍了Java Fast IO in ICPC实现源码,具有一定参考价值,需要的朋友可以了解下。
本文将介绍Java在ICPC快速IO实现方法,下面看看具体代码。
不处理EOF:
import java.io.OutputStream; import java.io.IOException; import java.io.InputStream; import java.io.PrintWriter; import java.util.Arrays; import java.util.Random; import java.io.IOException; import java.io.InputStreamReader; import java.util.StringTokenizer; import java.io.BufferedReader; import java.util.Comparator; import java.io.InputStream; /** * Built using CHelper plug-in * Actual solution is at the top */ 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); TaskD solver = new TaskD(); solver.solve(1, in, out); out.close(); } static class TaskD { public void solve(int testNumber, 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()); } } }
处理EOF:
import java.io.OutputStream; import java.io.IOException; import java.io.InputStream; import java.io.PrintWriter; import java.math.BigInteger; import java.util.Arrays; import java.util.Random; import java.io.IOException; import java.io.InputStreamReader; import java.util.StringTokenizer; import java.io.BufferedReader; import java.util.Comparator; import java.io.InputStream; /** * Built using CHelper plug-in * Actual solution is at the top */ 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); TaskD solver = new TaskD(); solver.solve(1, in, out); out.close(); } static class TaskD { public void solve(int testNumber, InputReader in, PrintWriter out) { while(in.hasNext()) { int a=in.nextInt(); int b=in.nextInt(); System.out.println(a+b); } } } static class InputReader { public BufferedReader reader; public StringTokenizer tokenizer; public InputReader(InputStream stream) { reader = new BufferedReader(new InputStreamReader(stream), 32768); tokenizer = null; } public boolean hasNext() { while (tokenizer == null || !tokenizer.hasMoreTokens()) { try { String line = reader.readLine(); if(line == null) return false; tokenizer = new StringTokenizer(line); } catch (IOException e) { throw new RuntimeException(e); } } return true; } public String next() { return tokenizer.nextToken(); } public int nextInt() { return Integer.parseInt(next()); } } }
