[英]Read hex file in java and traduce it into ascii
早上好,我有一個嚴重的問題。 我需要以十六進制讀取文件並將其轉換為ascii。 我還需要在另一個文件上寫ascii。 我是這樣嘗試的:
/**
* @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;
}
問題是我讀取了錯誤的值,例如讀取83 bat原始文件包含84
此代碼將讀取您的HEx輸入文件並以ASCII字符寫入文件
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();
}
