The list of methods to do DataOutputStream Write String are organized into topic(s).

Method

voidwriteString(DataOutputStream buf, String value)
write String 
if (value.contains("\0")) {
    throw new IllegalArgumentException("Null characters are not allowed in null-terminated strings.");
buf.writeBytes(value);
buf.writeByte((byte) 0);
voidwriteString(DataOutputStream os, String s)
write String to DataOutputStream motivation: DataInputStream.readUTF can't print lines larger than USHORTMAX 
if (s == null) {
    os.writeInt(-1);
} else {
    byte array[] = s.getBytes();
    os.writeInt(array.length);
    os.write(array);
voidwriteString(DataOutputStream os, String str)
Writes string into DataOutputStream. 
if (str != null) {
    os.writeInt(str.length());
    os.writeChars(str);
} else {
    os.writeInt(0);
voidwriteString(DataOutputStream out, String s)
write String 
boolean isNull = s == null;
out.writeBoolean(isNull);
if (!isNull) {
    out.writeUTF(s);
voidwriteString(DataOutputStream out, String str)
Writes a string to the buffer. 
int len = str.length();
if (len >= 65536) {
    throw new IllegalArgumentException("String too long.");
out.writeShort(len);
for (int i = 0; i < len; ++i) {
    out.writeChar(str.charAt(i));
voidwriteString(DataOutputStream out, String str)
write String 
byte[] b = str.getBytes();
out.writeInt(b.length);
out.write(b);
voidwriteString(DataOutputStream out, String str)
Writes a string to a DataInputStream. 
out.writeShort(str.length());
for (char letter : str.toCharArray()) {
    out.writeChar(letter);
voidwriteString(DataOutputStream out, String text)
Writes a string to the given output stream and emits an additional short to transfer if text is null. 
if (null == text) {
    out.writeShort(0);
} else {
    out.writeShort(1);
    out.writeUTF(text);
voidwriteString(DataOutputStream out, String theString)
Write a string. 
if (theString == null) {
    out.writeInt(-1);
} else {
    int len = theString.length();
    out.writeInt(len);
    writeCharsOfString(out, theString);
voidwriteString(DataOutputStream out, String val)
write String 
out.writeUTF(val);
