     i == j-- means i == j; j = j - 1;

     i == j-1 means i == (j-1);

     i == --j means j = j - 1; i == j;

     Here is the operator precedence table, in order from highest to lowest. For example, - has higher precedence than ==, which is why i==j-1 means i==(j-1)

   • What is java.io.Reader transferTo(java.io.Writer) method in Java 10 ? Is there a similar method for InputStream?

     Top Answer

     Answered May 17, 2018 · 5 votes

     There is such method in InputStream since Java 9: InputStream.transferTo()

     Also, for earlier versions of JDK, there is IOUtils.copy(InputStream input, OutputStream output)

     in apache-commons-io library.

     Documentation says:

     Copies bytes from an InputStream to an OutputStream

     So, it should do the same thing.

   • what is the difference for java using in windows and linux. I am new to java. where can i start for programming in java

     A good place to start would be the Java Tutorials.

     As for the difference between Windows and Linux, you are unlikely to encounter much differences if you use the language right. This of course assumes that you handle file paths properly instead of assuming / or \ as path separator or a common file system root. There are also some things that may not work exactly alike but those cases are rare and mostly only relevant in larger applications or frameworks.

   • What is the use of the Console class in java? Is it referring to the java control panel console? Please explain in detail

     Top Answer

     Answered Oct 26, 2011 · 3 votes

     Roughly: the console = the terminal = the command line.

     That is the (usually) black screen that you can use to start your program (with java YourClass), and where you can read parameters from or write to.

     The Console object is an easier-to-use alternative to System.in and System.out

   • What is ".in" file in java that is for inputs?

     Top Answer

     Answered Dec 19, 2012 · 11 votes

     The ".in" file extension doesn't have any special meaning as far as Java or C++ is concerned. It's just an extension to indicate (to humans) that it is an input file.

   Oct 26, 2023 · In Java, the ‘+=’ represents the additional assignment operator and is used to add the right operand to the left operand and assign the result back to the left operand, with the syntax, operandA += operandB. It’s a shorthand for a common operation that can make your code more concise and easier to read. Here’s a simple example: int a = 5; a += 3;
