Java编程在ICPC快速IO实现源码

        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());
 } 
 }
}

 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());
 }
 }
}
