Java equivalent to Explode and Implode(PHP)

The Javadoc for String reveals that String.split() is what you're looking for in regard to explode.

Java does not include a "implode" of "join" equivalent. Rather than including a giant external dependency for a simple function as the other answers suggest, you may just want to write a couple lines of code. There's a number of ways to accomplish that; using a StringBuilder is one:

String foo = "This,that,other";
String[] split = foo.split(",");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < split.length; i++) {
    sb.append(split[i]);
    if (i != split.length - 1) {
        sb.append(" ");
    }
}
String joined = sb.toString();

String.split() can provide you with a replacement for explode()

For a replacement of implode() I'd advice you to write either a custom function or use Apache Commons's StringUtils.join() functions.

Good alternatives are the String.split and StringUtils.join methods.

Explode :

String[] exploded="Hello World".split(" ");

Implode :

String imploded=StringUtils.join(new String[] {"Hello", "World"}, " ");

Keep in mind though that StringUtils is in an external library.
