BufferedReader类型为什么转化成INT类型,返回时返回的不是INT型而是乱码?

这是我的代码,希望能从指定文件读入数据后转换成INT型并返回
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class EightPuzzle{
private int thePuzzle[] = new int[9];
/***
* Constructor which reads in tile values from standard input
*/
public static void main (String[] args)
{EightPuzzle start= new EightPuzzle();
int []i = start.Puzzle();
System.out.print(i);}
public int[] Puzzle()
{
BufferedReader in = new BufferedReader(
new InputStreamReader( System.in ) );
for (int j=0; j<9; j++)
{
try
{
thePuzzle[j] = Integer.parseInt(in.readLine());
}
catch(Exception e)
{
}
if ( thePuzzle[j] > 8 || thePuzzle[j] < 0)
{
System.err.print("The tile number must be an");
Sys
import java.io.BufferedReader;

public class EightPuzzle{
private int thePuzzle[] = new int[9];
/***

for (int j=0; j<9; j++)
{
try
{
thePuzzle[j] = Integer.parseInt(in.readLine());
}
catch(Exception e)
{
}
if ( thePuzzle[j] > 8 || thePuzzle[j] < 0)
{
System.err.print("The tile number must be an");
Sys
不好意思 我从你代码没有看到 从文本里面读入数据
只看到你是从 System.in 从键盘读
...厄 我加点注释吧..
BufferedReader in = new BufferedReader(
new FileReader( "1.txt" ) );
//把你的文本信息读出来..假设只有一行
String tempStr = in.readLine();
//如果没读倒nums赋值null,读倒后按空格分离这些数字
//例如0 2 3 4 5
//nums里面就放了nums[0]=0 以此类推
String [] nums = tempStr != null? tempStr.split("\\s"):null;
if(nums !=null){
for(String num : nums){
System.out.print(Integer.parseInt(num));
}
}
换成while循环
String str = null;
while((str=is.readLine())!=null){
}
java的BufferedReader类
BufferedReader类的对象建立问题(JAVA语言)
【java】BufferedReader的问题
BufferedReader reader = new BufferedReader(new FileReader(file));
java中的bufferedreader br=new bufferedreader()是什么意思
JAVA问题:BufferedReader file = new BufferedReader(new FileReader(path))总是出错这是为何?
Java 编程 通过Bufferedreader捕获所输入的语句
()类()()
类噢噢类噢噢类噢噢
