Java Language Project

The original name of the Java language project was "Oak."
The project was initiated by James Gosling in June 1991.

Java 1.0 Release

Sun Microsystems released the first public implementation of Java, known as Java 1.0, in 1996.

Operator Precedence

In Java, the operator with the highest precedence is the post-increment operator ++.

Output of Expressions

In the 'OperatorExample' class, the expression System.out.println(+ +x) outputs the value of x without any changes, as the unary plus operator does not affect the value.

Switch Statement Output

In the 'SwitchExample' class, if the variable 'number' is 25, it falls in the default case, typically producing a message indicating that the number is not a specified case.

Minimum Value Calculation

In the 'OperatorExample' class, if 'a' is set to 20, the variable 'min' will hold the value of 10, assuming the context is checking for a minimum with another number.

Data Types in Java

The non-primitive data type in Java from the options given is typically "String," while the others such as int, float, and boolean are primitive data types.

Int Data Type Size

The default size of the 'int' data type in Java is 32 bits (4 bytes).

Arithmetic Evaluation

The result of the expression $5(7 + 3) in Java evaluates to $50, as the expression inside the parentheses equals 10 and is then multiplied by 5.

This quiz covers the history of Java, introduction to Java programming, byte code, JVM & JDK, data types, operators, and various control statements like if-else, switch, while, do-while, for loop, break, and continue. It also discusses the initial development of Java by James Gosling, Mike Sheridan, and Patrick Naughton.
