[英]Read hex file in java and traduce it into ascii
Good Morning i have a serius problem. 早上好,我有一个严重的问题。 I need to read a file in hex and translate it into ascii.
我需要以十六进制读取文件并将其转换为ascii。 I also need to write the ascii on another file.
我还需要在另一个文件上写ascii。 I tried so:
我是这样尝试的:
/**
* @param args the command line arguments
*/
public static void main(String[] args) throws FileNotFoundException, IOException {
FileInputStream in = new FileInputStream("fileAscii");
int read;
String hex = "";
int count = 0;
String valueRead="";
PrintWriter writer= new PrintWriter("fileOutput");
while ((read = in.read()) != -1) {
count++;
valueRead= Integer.toHexString(read);
if(valueRead.length()==1){
hex=hex+"0";
}
hex = hex + valueRead;
if (is16Multipler(count)) {
System.out.println(hex);
String sb = "";
StringBuilder temp = new StringBuilder();
for (int i = 0; i < hex.length() - 1; i += 2) {
//grab the hex in pairs
String output = hex.substring(i, (i + 2));
//convert hex to decimal
int decimal = Integer.parseInt(output, 16);
//convert the decimal to character
sb=sb+(char) decimal;
}
if(!sb.equals("00000000000000000000000000000000"))
{
writer.println(sb.toString());
}
hex = "";
}
}
}
public static boolean is16Multipler(int number) {
if (number % 16 == 0) {
return true;
}
return false;
}
the problem is that I read the wrong values for example read 83 bat the original file contains 84 问题是我读取了错误的值,例如读取83 bat原始文件包含84
This code will read your input fileof HEx and write into a file as ASCII characters 此代码将读取您的HEx输入文件并以ASCII字符写入文件
public static void main(String[] args) throws FileNotFoundException, IOException {
BufferedReader br = new BufferedReader(new FileReader("fileAscii")); // to read a single line from the file
int read;
String src= new String(); // to store the string obtained from buffered reader
PrintWriter writer= new PrintWriter("fileOutput");
src=br.readLine(); // read an input line from the file
while(src!=null){
src=src.replace(" ", ""); // Trim out the spaces
for(int i=0;i<src.length();i+=2){
read=Integer.parseInt(src.substring(i,i+2), 16); // convert the String to hex integer
writer.print((char)read); // convert hex to char and write into file
}
src=br.readLine();
}
writer.flush();
}
