There are more than 1 commands in the Java 8 foreach function

Is it possible to import the map.xml in Java 8 Multiple commands used in foreach function?

So instead of:

map.forEach((k,v) -> 
System.out.println(k + "=" + v));

What I want to do is as follows:

map.forEach((k,v) -> 
System.out.println(k)),v.forEach(t->System.out.print(t.getDescription()));

Let's assume that K is a string and V is a set

Solution

Lambda syntax allows two body definitions:

>The expression returned by a single value, for example: X – > x * 2 > multiple statements, enclosed in curly braces, for example: X – > {x * = 2; returns X;}

The third special case is that it allows you to avoid using curly braces when calling the void return method, such as system. X – > out. println(X).
