The nextLong() method is used to return the next pseudorandom, uniformly distributed long value from this random number generator's sequence.. The wrapper class for long is Long. Similarly, LongStream.range () and LongStream.rangeClosed () methods are invoked next. In this tutorial we discussed Java's primitive or basic data types their default values and range. What happens when the string contains a number that is not in the range of the short? It is also known as implicit type casting or type promotion. The java.util.Scanner.nextLong()method scans the next token of the input as a long.An invocation of this method of the form nextLong() behaves in exactly the same way as the invocation nextLong(radix), where radix is the default radix of this scanner.
