Lambda Expressions27:40
Lambda Expression Syntax:
Below is syntax of Lambda,
(argument-list) -> {body}
Where as
1) Argument-list: can be zero or more arguments
2) Arrow-token: It is mandatory, and separates arguments and body of expression.
3) Body: can contain zero or more statements
Lambda without Parameter
() -> {
//Body of no parameter lambda
}
Lambda with single argument
(p1) -> {
//Body of single parameter lambda
}
Lambda with two arguments
(p1,p2) -> {
//Body of multiple parameter lambda
}
Similarly Lambda can have any number of arguments
How above Lambda, can be used:
For example, Lambda can be used in TreeSet, to specify sorting order of element.
Below is syntax, for TreeSet, to sort in descending order
TreeSet<String> tss = new TreeSet<>((s1,s2)->s2.compareTo(s1));
Above can be rewritten as
TreeSet<String> tss = new TreeSet<>((s1,s2)->{ return s2.compareTo(s1); } );
So, when there is only single return statement, { } & and explicit return are not required.

Lambda expression is a compact form of Anonymous Inner class, and advantage of using Lambda is, it’s make Code more Compact

TreeSet, example in previous, can be rewritten as

TreeSet<String> tss = new TreeSet<>( new Comparator(){ public int compare(String s1, String s2){
return s1.compareTo(s2);
}});
