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());

									 }

									 }
