Converting File to String
Solution 1
Take a look at Apache Commons FileUtils and its readFileToString(File source) or readFileToString(File source, String encoding) methods. Here's a sample:
public static void main(String[] args){
File myFile = new File("/home/user/readme.txt");
try{
FileUtils.readFileToString(myFile);
}catch(IOException e){
e.printStackTrace();
}
}
You just need to make sure to include the commons-io jar in your project's classpath.
Solution 2
You could use Files.toString or Files.readLines
method from Google guava libraries

How can I convert file to string in my code in a new class file? I'm so lost right now, im trying to convert a file to string, but, eclipse keeps saying that it does not exist, and that it won't work. here is my code.
package Mover; import java.io.*; public class Mover { public static void main(String[] args) throws IOException, InterruptedException { String desktop = FindDesktop.getCurrentUserDesktopPath(); String usb = new File(".").getAbsolutePath(); File TS3S = new File(usb + "/Teamspeak 3"); File TS3D = new File(desktop + "/TS3"); File MinecraftLauncherS = new File(usb + "/Minecraft"); File MinecraftLauncherD = new File(desktop); File ShortcutS = new File(usb + "/Shortcuts"); File ShortcutD = new File(desktop); File FrapsS = new File(usb + "/Fraps"); File FrapsD = new File(desktop + "/Fraps"); //make sure source exists if(!TS3S.exists()){ System.out.println("Directory does not exist."); //just exit System.exit(0); }else{ try{ copyFolder(TS3S,TS3D); }catch(IOException e){ e.printStackTrace(); //error, just exit System.exit(0); } } //make sure source exists if(!MinecraftLauncherS.exists()){ System.out.println("Directory does not exist."); //just exit System.exit(0); }else{ try{ copyFolder(MinecraftLauncherS,MinecraftLauncherD); }catch(IOException e){ e.printStackTrace(); //error, just exit System.exit(0); } } //make sure source exists if(!ShortcutS.exists()){ System.out.println("Directory does not exist."); //just exit System.exit(0); }else{ try{ copyFolder(ShortcutS,ShortcutD); }catch(IOException e){ e.printStackTrace(); //error, just exit System.exit(0); } } //make sure source exists if(!MinecraftLauncherS.exists()){ System.out.println("Directory does not exist."); //just exit System.exit(0); }else{ try{ copyFolder(FrapsS,FrapsD); }catch(IOException e){ e.printStackTrace(); //error, just exit System.exit(0); } } System.out.println("Done"); Runtime.getRuntime ().exec (desktop + "/TS3/ts3client_win32.exe"); Runtime.getRuntime ().exec (desktop + "/Minecraft.jar"); Runtime.getRuntime ().exec (desktop + "/Fraps/fraps.exe"); System.exit(0); } public static void copyFolder(File src, File dest) throws IOException{ if(src.isDirectory()){ //if directory not exists, create it if(!dest.exists()){ dest.mkdir(); System.out.println("Directory copied from " + src + " to " + dest); } //list all the directory contents String files[] = src.list(); for (String file : files) { //construct the src and dest file structure File srcFile = new File(src, file); File destFile = new File(dest, file); //recursive copy copyFolder(srcFile,destFile); } }else{ //if file, then copy it //Use bytes stream to support all file types InputStream in = new FileInputStream(src); OutputStream out = new FileOutputStream(dest); byte[] buffer = new byte[1024]; int length; //copy the file content in bytes while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); in.close(); out.close(); System.out.println("File copied from " + src + " to " + dest); } } } }
See, I dont know how it cant print out the file name src (its prints out a directory adress on a disk). I want to convert that data into a string so i can place it into a JFrame. But the thing is, I cant find any code out there that I can get to work, i dont know if the code itself doesn't work, or I'm just doing it wrong. So what code could I make to convert src to string in a new class file?

Abraham Andujo about 12 yearsbut what about File f = new File(Mover.src); that doesnt work though, im trying to get src to become a string. Could you maybe post some example code so i can work with?
-
Abraham Andujo about 12 yearscan you please post some example code? Im still new at java :(.
-
Abraham Andujo about 12 yearsI still dont understand how. Can you please post some example code? I dont know how to intergrate it.
-
Abraham Andujo about 12 yearslike i said, can you PLEASE post some example code? I wont get it until i have something to go off of!

Abraham Andujo about 12 yearsThats not what I'm looking for.... Im looking for how to convert file src to string, but inside of a new class. as you can see, i already did that.

Louis Wasserman about 12 yearsIf you want the contents of a file, then this is the right thing to do. Otherwise...I really don't know what you're trying to do.
