Provide text parsing and formatting support for proto2 instances. For our example, we will read LICENSE.txt from the hamcrest-library-1.3.jar file: Test public void givenFileNamewhenUsingJarFile. To read a file which is located inside a JAR file, we will need a JAR with a file inside it. Reading a File from a JAR. Here we used the URL and URLConnection class available in the standard SDK.

The type of length is integer and is serialized using zero-compressed format. It provides methods to serialize, deserialize, and compare texts at byte level. Let's take an example.This class stores text using standard UTF8 encoding. Nested Class Summary.The Scanner class of the java.util package is used to read input data from different sources like input streams, users, files, etc.

The method is terminated when it encounters a next line character, .Recommended Reading: Java Scanner skipping the nextLine().Java Scanner with BigInteger and BigDecimalJava scanner can also be used to read the big integer and big decimal numbers. Once the whitespace is encountered, it returns the string (excluding the whitespace).Example 5: Java Scanner nextLine() import java.util.Scanner System.out.println('Using nextLine(): ' + value) In the first example, we have used the nextLine() method to read a string from the user.Unlike next(), the nextLine() method reads the entire line of input including spaces. However, the next() method only reads the first name.This is because the next() method reads input up to the whitespace character. // read input from the input streamScanner sc1 = new Scanner(InputStream input) Here, we have created objects of the Scanner class that will read input from InputStream, File, and String respectively.The Scanner class provides various methods that allow us to read inputs of different types.Example 2: Java Scanner nextInt() import java.util.Scanner System.out.println('Enter an integer: ') System.out.println('Using nextInt(): ' + data1) In the above example, we have used the nextInt() method to read an integer value.Example 3: Java Scanner nextDouble() import java.util.Scanner System.out.print('Enter Double value: ') System.out.println('Using nextDouble(): ' + value) In the above example, we have used the nextDouble() method to read a floating-point value.Example 4: Java Scanner next() import java.util.Scanner System.out.println('Using next(): ' + value) In the above example, we have used the next() method to read a string from the user.Here, we have provided the full name. Import java.util.Scanner To learn more about importing packages, visit Java Packages.Once we import the package, here is how we can create Scanner objects.

For example,Suppose there is an input string: He is 22In this case, the scanner object will read the entire line and divides the string into tokens: ' He', ' is' and ' 22'. Tokens are small elements that have some meaning to the Java compiler. nextBigDecimal() - reads the big decimal value from the userExample 4: Read BigInteger and BigDecimal import java.math.BigDecimal System.out.print('Enter a big integer: ') BigInteger value1 = input.nextBigInteger() System.out.println('Using nextBigInteger(): ' + value1) System.out.print('Enter a big decimal: ') BigDecimal value2 = input.nextBigDecimal() System.out.println('Using nextBigDecimal(): ' + value2) In the above example, we have used the java.math.BigInteger and java.math.BigDecimal package to read BigInteger and BigDecimal respectively.The Scanner class reads an entire line and divides the line into tokens.
