Explode and Implode (like PHP) in Java

Question

I am new to Java, although I had good experience in PHP and am looking for the perfect replacement for the Explode and implode functions (available in PHP) in Java.

I have Googled for the same, but not happy with the results. Anyone have a good solution for my problem would be appreciated.

Answer 1

Javadoc for String shows that String.split() is what you are looking for in relation to explode .

Java does not include the "implode" equivalent of "join". Instead of including a giant external dependency for a simple function, as other answers suggest, you can simply write a couple lines of code. There are several ways to do this; using 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(); 

Answer 2

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

To replace implode() I would advise you to write either a user-defined function or use the Apache Commons StringUtils.join() functions.

Answer 3

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

Explosion:

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

Implode:

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

Keep in mind that StringUtils is in an external library.

Answer 4

java.lang.String.split(String regex) is what you are looking for.

Answer 5

I am not familiar with PHP, but I think String.split is Java, equivalent to PHP explode . As for implode , the standard library does not provide such functionality. You just iterate over the array and build the string using StringBuilder / StringBuffer . Or you can try the excellent Google Guava Splitter and Joiner or split/join from Apache Commons StringUtils .

Answer 6

if you speak in reference to String Class. so you can use

substring / split

for Explode and using String

concate

for implode.
