请教大家一个关于，数据类型错误的问题

编译软件提示

The method readInt() in the type DataInputStream is not applicable for the arguments (int)

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
  public class ArrayTest {
  public static void main( String args[] ) {
    int data[] = {100,101,102,103,104,105};
    int t;
try
{ DataOutputStream out = new  DataOutputStream (new  FileOutputStream("C:\\Dest.txt"));
  for(int i=0;i<data.length;i++) 
    out.writeInt(data[i]);
  out.close();
 DataInputStream in = new  DataInputStream (new  FileInputStream("C:\\Dest.txt"));
 for(int i= data.length-1;i>= 0;i--) {
    t=in.readInt(int data[i]);
    System.out.print(" "+t);
    }
  System.out.println( );
  in.close();
}catch(IOException e)
{ System.out.println(e.getMessage());}
  }
}

看下API，readInt是不需要参数的

[qq_29041041]

如果没有参数那么才可以怎么反顺序输出呢?

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class Test
{
public static void main(String args[])
{
int data[] = { 100, 101, 102, 103, 104, 105 };
int t;
String content="";
try
{
DataOutputStream out = new DataOutputStream(new FileOutputStream(
"C:\\Dest.txt"));
for (int i = 0; i < data.length; i++)
out.writeInt(data[i]);
out.close();
DataInputStream in = new DataInputStream(new FileInputStream(
"C:\\Dest.txt"));
for (int i = 0; i < data.length; i++)
{
t = in.readInt();
content=t+" "+content;
}
System.out.print(content);//反顺序逻辑
in.close();
}
catch (IOException e)
{
System.out.println(e.getMessage());
}
}
}

搞好了 原来这样写就行了 还得多学习
