What is the Java ?: operator called and what does it do? In particular, if Java ever gets another ternary operator, people who use the term "conditional operator" will still be correct and unambiguous - unlike those who just say "ternary operator" Yes, the phrase "ternary operator" has stuck - my answer is part of an effort to "unstick" it, just as I try to correct the claim that "objects are passed by reference"
What is the difference between == and equals () in Java?

java - (AND) and || (OR) in IF statements - Stack Overflow An interesting fact is that Java also uses the and | as logic operands (they are overloaded, with int types they are the expected bitwise operations) to evaluate all the terms in the expression, which is also useful when you need the side-effects
What does the ^ operator do in Java? - Stack Overflow Exponentiation in Java As for integer exponentiation, unfortunately Java does not have such an operator You can use double Math pow(double, double) (casting the result to int if necessary) You can also use the traditional bit-shifting trick to compute some powers of two That is, (1L << k) is two to the k-th power for k=0 63 See also
What is the difference between and in Java? I always thought that operator in Java is used for verifying whether both its boolean operands are true, and the operator is used to do Bit-wise operations on two integer types Recently I came to know that operator can also be used verify whether both its boolean operands are true , the only difference being that it checks the RHS operand even if the LHS operand is false
java - SSL and cert keystore - Stack Overflow again, yes Java JDK tools can work with SSL self signed certs It also works in Windows 11 just use Oracle's JDK kit path C:\Program Files\Java\jdk-20\lib\security\cacerts tool path C:\Program Files\Java\jdk-20\bin\keytool I just drop the cert I need into the folder named security and run similar commands as the imac just different paths
logging - How to use log levels in java - Stack Overflow The java util logging Level documentation does a good job of defining when to use a log level and the target audience of that log level Most of the confusion with java util logging is in the tracing methods It should be in the class level documentation but instead the Level FINE field provides a good overview:
Setting JAVA_HOME - Stack Overflow JRE_HOME if you installed the JRE (Java Runtime Environment) In the Variable Value field, enter your JDK or JRE installation path Open Command Prompt as Administrator Set the value of the Environment variable to your JDK (or JRE) installation path as follows: setx -m JAVA_HOME "C:\path_to_Java\jdk_version"
