Following example demonstrates how to monitor a thread's status by extending Thread class and using currentThread.getName() method.

In below program, we are not handling the exception with try-catch block but we are adding throws clause in the method declaration. How to monitor a thread's status Solution. This is very much similar to FileInputStream but JVM treats it differently. Now we will look at java program using character stream to read the file.

Since one of the main purposes of Java is to support the “write once, run anywhere” philosophy, it was necessary to include direct I/O support for characters. While the byte stream classes provide sufficient functionality to handle any type of I/O operation, they cannot work directly with Unicode characters. If File is missing from root directory, we will get following error.Īfter Creating file in project root directory, we will get file content as output. Istream = new FileInputStream(inputFile) While working with stream classes we have to take care of checked exceptions, In our program, we are doing it using a try-catch block. The second method has some benefits: if you create a File object, you can use the File class methods, such as exists()and lastModified(), to retrieve file information. Then, you can pass the File object to the constructor of the FileInputStream class. class using the standard java compiler javac. You can create a File object by passing the filename to the File constructor.You can pass the filename to the constructor of the FileInputStream class. class using the standard java compiler javac.Let’s understand way to associate a File object with the input stream: We will write a java program to read from file and print file data on the user screen. So even though Java 7 comes with a low-level API to watch for file system changes.
