Method

Stringload(File file, String encoding)
Read a text file into a string. 
FileInputStream fis = new FileInputStream(file);
InputStreamReader reader = new InputStreamReader(fis, encoding);
StringBuffer strBuf = new StringBuffer();
char[] buffer = new char[4096];
int i = 0;
try {
    while ((i = reader.read(buffer)) != -1)
        strBuf.append(buffer, 0, i);
...
Tload(final File file, final Class clazz)
load 
InputStream stream = null;
try {
    stream = new FileInputStream(file);
    if (stream != null)
        return load(stream, clazz);
} finally {
    try {
        if (stream != null)
...
char[]load(String fileName)
load 
File file = new File(fileName);
final int size = (int) file.length();
char[] buffer = new char[size];
try (InputStreamReader in = new InputStreamReader(new FileInputStream(file))) {
    int readSize = in.read(buffer);
    if (readSize < size) {
        buffer = Arrays.copyOf(buffer, readSize);
    return buffer;
} catch (IOException e) {
return null;
StringloadAsText(InputStream in, String encoding, int bufferSize)
load As Text 
InputStreamReader reader = new InputStreamReader(in, encoding);
char[] buffer = new char[bufferSize];
int offset = 0;
for (;;) {
    int remain = buffer.length - offset;
    if (remain <= 0) {
        char[] newBuffer = new char[buffer.length * 2];
        System.arraycopy(buffer, 0, newBuffer, 0, offset);
...
Object[]readFile(Class cl, String filename)
Lire un fichier texte # partir Retourne un liste de chaque ligne 
Object[] res = null;
ArrayList list = new ArrayList();
String nextLine = null;
try {
    BufferedReader in = new BufferedReader(
            new InputStreamReader(cl.getResourceAsStream("/res/" + filename)));

...
StringreadFile(Class cls, String filename)
read File 
InputStream stream = cls.getResourceAsStream(filename);
if (stream != null) {
    StringBuffer fileData = new StringBuffer();
    BufferedReader reader = new BufferedReader(new InputStreamReader(stream));
    char[] buf = new char[1024];
    for (int bufLen = reader.read(buf); bufLen != -1; bufLen = reader.read(buf)) {
        String readData = String.valueOf(buf, 0, bufLen);
        fileData.append(readData);
...
StringreadFile(ClassLoader classloader, String filename)
Just for reading a damn file from a package using class loader. 
InputStream istream = classloader.getResourceAsStream(filename);
if (istream == null)
    return null;
BufferedReader reader = new BufferedReader(new InputStreamReader(istream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
    while ((line = reader.readLine()) != null) {
...
StringreadFile(File f)
read File 
BufferedReader reader = null;
StringBuilder sb = new StringBuilder();
try {
    reader = new BufferedReader(new InputStreamReader(new FileInputStream(f), "utf-8"));
    String line = null;
    while ((line = reader.readLine()) != null)
        sb.append(line);
} catch (Exception e) {
...
StringreadFile(File f)
read File 
return read(new FileInputStream(f));
StringreadFile(File f)
read File 
return readStream(new InputStreamReader(new FileInputStream(f), "UTF-8"));
