This shorthand can greatly reduce the length of the output in the common case where a wrapped exception is thrown from same method as the "causative exception" is caught. The above example was produced by running the program: public class Junk { public static void main(String args[]) { ...
The ternary operator is a shorthand way of writing an if-else statement. It’s less readable than both if-else and switch statements, but it can be very concise. Here’s an example: intnum=2;Stringresult=(num==1)?'One':(num==2)?'Two':'Not one or two';System.out.println(result...
We canuse a ternary operatoras a shorthand expression that works like anif/elsestatement. Let's see ourif/elseexample again: if(count >2) { System.out.println("Count is higher than 2"); }else{ System.out.println("Count is lower or equal than 2"); } ...
The -deprecation option is shorthand for -Xlint:deprecation. --enable-preview Enables preview language features. Used in conjunction with either -source or -- release. -encoding encoding Specifies character encoding used by source files, such as EUC-JP and UTF-8. If the -encoding option isn't...
