Add the following: local variable declarations (with or without initializers) expression statements comprising: calls to methods, method references and lambdas; new ...

Apr 26, 2012 · @Cleb Theoretically there's no difference, but compilers may optimize the two statements differently (making different assumptions about branch prediction). Most people don't need to worry about that level of optimization, and if you do, you probably want to use attributes like __builtin_expect anyway. –

WARNING As mentioned in comments, Using peek() for production code is considered bad practice The reasson is that "According to its JavaDocs, the intermediate Stream operation java.util.Stream.peek() “exists mainly to support debugging” purposes."
