inputnum.java

200多个自己编的java程序,大家可以学一下.

package num;
import java.io.*;
 public class InputNum{
 private int i;
 public int getnum(){
 	
 
   try{
   	InputStreamReader ir;
   	BufferedReader in;
   	ir=new InputStreamReader(System.in);
   	//from key geta string and creat a StringStream
   	in=new BufferedReader(ir);
   	String s=in.readLine();
   	//read a line from in
    i=Integer.parseInt(s);//change to int
 
  }
   catch(IOException e)
   {
   	System.out.println(e);
   }
  return i;

  }
