Replace a Substring of a String in Velocity Template Language

Question

I want to replace a part of a string in Velocity Template Language with another string.

For Example:

#set($a = "Hello") #set($b = "+") 

I want to replace ll in Hello with ++. The output should be He++o

Please help me

Thanks Kishore

By default you can use the methods of the Java String object:

#set( $a = "Hello" ) #set( $b = $a.replace("l", "+") ) ${b} 

will produce He++o and you can also use velocity variables as arguments to your method calls, e.g.:

#set( $a = "Hello" ) #set( $b = "+" ) #set( $c = $a.replace("l", ${b}) ) ${c}
