Java Tutorial

If we are required to check whether or not, the data entered by the user is of the type boolean, we can use the hasNextBoolean method. Simply, we are checking if the data entered by the user is boolean or not. Checking if the user input is boolean type(hasNextBoolean method) This method returns true if […]

hasNextByte Method If we are required to check whether the given data entered by the user, is of type byte, then we can make use of the hasNextByte method. This method returns true, if the user input was a byte type, and else, the method gives false. Checking if the user input is byte type(hasNextByte

The hasNext method in Java With this method, we get true as an output if there is some input by the user, else, we get false as an output. This method is also very simple to be used. Check if there is a token in its input (hasNext method) Let’s have a look at an

The hasNextInt method in Java Well, sometimes, we are required to check whether or not the user has input some valid integer type data. In such situations, we can make use of the method hasNextInt, through which, the user will input something, and then it will be checked by this method, whether the given input

The NextDouble-Method in Java Sometimes, we might require to get the double type data from the user (decimal numbers in short). In such situations, we can make use of the nextDouble method, if we want to get the data as a double type value. Getting a double type data as user input (NextDouble-Method) package com.company;import

The NextShort method in java Using the NextShort method, we can get the short type data as user input. So, in some situations, where we are required to take the short type data as user input, we can make use of the NextShort method. Let’s have a look at a simple program, in which, we

The next byte method If we are required to get the user input in form of a byte, we can make use of the next byte method here. So, below is the implementation of the next byte method, where we are trying to get a byte as input from the user. Java Scanner nextByte() method

The nextBoolean method Well, sometimes, we are required to get the user input in the form of true, or false. In such a situation, we can make use of the next boolean method, with which, we can get boolean input from the user. For example, if the user is asked that is he/she above 18

The nextLine method in Java As we can get from the name, we can simply say that we are going to get the line as an input. So, whenever we are in such a situation, that we need some line from the user as input, we can make use of the nextLine method. Below is

Next method Now let’s discuss the next() method, with which we can take a complete token as an input from the user. This method returns the next complete token from the Scanner. Get a complete token as input (next method) Have a look at the below program which demonstrates the use of the next() method
