It is a block of code that can be assigned to a variable or passed as an argument to a method or passed as an argument to another lambda expression just like any other data. The code can also be invoked whenever required. The main motivation behind supporting this in java is to remove ...
Java Programming Language Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) mor...

For an even shorter expression, use it when there is only a single parameter in the lambda function: val positives = list.filter { it > 0 } Traversing a map/list of pairs in Kotlin for ((k, v) in map) { println(“$k -> $v”) } k and v can be called anything. Using ranges...
