Java uses call by value.

• Java passes a copy of the value of a variable to a method, not the actual variable itself.

• Changes made to the parameter inside the method have no effect on the original variable.

• However, if the parameter is an object reference, the reference is passed by value, so changes to the object itself will be reflected outside the method.

Java is platform-independent due to its bytecode and virtual machine architecture.

• Java code is compiled into bytecode, which can run on any platform with a Java Virtual Machine (JVM).

Swapping numbers can be done using a temporary variable, arithmetic operations, or XOR bitwise operator.

• Using a temporary variable: temp = a; a = b; b = temp;

• Using arithmetic operations: a = a + b; b = a - b; a = a - b;

• Using XOR bitwise operator: a = a ^ b; b = a ^ b; a = a ^ b;

Overloading is using the same method name with different parameters. Overriding is replacing a method in a subclass.

• Overloading is used to have multiple methods with the same name but different parameters.

• Overriding is used to replace a method in a subclass with a new implementation.

• Overloading is resolved at compile-time while overriding is resolved at runtime.

• Example of overloading: public void print(int num) and public void print(String str)

• Example of overriding: public cl...read more

Humming noise is generated due to the vibration of magnetic domains in a magnetic material.

• Magnetostriction is the property of magnetic materials to change their shape or dimensions when subjected to a magnetic field.

• This change in shape causes the magnetic domains to vibrate, which in turn generates a humming noise.

• The frequency of the humming noise is directly proportional to the frequency of the magnetic field.

• Magnetostriction is used in various applications such as in tra...read more
