peek<\/code> is just a way to peek<\/em> inside the stream, it doesn’t change it but the function in peek will receive all the elements that are in the stream.<\/p>\n

forEach<\/code> is an terminal operation that will consume all the data in the stream and return void<\/code>.<\/p>\n

The result of the above code will be each number printed twice, when you remove peek<\/code> you will get the numbers printed only once.<\/p>\n

If you remove forEach<\/code> you wont’ get any output because stream won’t execute the actions until the terminal operation (like e.g. forEach<\/code>, count<\/code>) is encountered.<\/p>\n<\/p><\/div>\n
