You can also do it without regex in a very simple way. First of all use indexOf() String method to find the index of the "~" character. Then use the substring() method to extract the string you are lookin for. Here is an example:

String stringToProcess = "hello~world";
int charIndex = stringToProcess.indexOf('~');
String finalString = stringToProcess.substring(0, charIndex);

Here is regular expression that you can use: ^(.*?)~.

However in your simple case you do not need regular expressions at all. Use indexOf() and substring():

int tilda = str.indexOf('~');
if (tilda >= 0) {
    word = str.substring(0, tilda);
}

Without regex it can be solved

Simply split your string by ~.

String str[] = "Worddjjfdskfjsdkfjdsj ~ Word ~ Word".split("~");
        System.out.println(str[0]);

You can use this regex to capture all character from start of string ^ to first occurrence of ~:

^[^~]*

[^~]* is negation based regex that matches 0 or more of anything but ~
