Compound Assignment Operators Sometime we need to modify the same variable value and reassigned it to a same reference variable. Java allows you to combine assignment and addition operators using a shorthand operator. For example, the preceding statement can be written as: i +=8; //This is sa...
You can also combine the arithmetic operators with the simple assignment operator to create compound assignments. For example, x+=1; and x=x+1; both increment the value of x by 1. The + operator can also be used for concatenating (joining) two strings together, as shown in the following...

so it will conveniently give you a compile-time error and catch the problem before you ever try to run the program. So the pitfall never happens in Java. (The only time you won’t get a compile-time error is when x and y are boolean, in ...
Assignment operator operates on both primitive and reference types. It has the following syntax: var = expression; Note that the type of var must be compatible with the type of expression. Chaining of assignment operator is also possible where we can create a chain of assignments in order to...
Exercises Change the following program to use compound assignments: class ArithmeticDemo { public static void main (String[] args){ int result = 1 + 2; // result is now 3 System.out.println(result); result = result - 1; // result is now 2 System.out.println(result); result = result...
The Object class can appear as a special case in inheritance functionality. The compiler bypasses type checking for assignments to and from variables that are declared to be of type Object. Some classes inherit from the Object class, some classes inherit from another class, and some classes don...

In Java, the operator “>>” is signed right shift operator. All integers are signed in Java, and it is fine to use >> for negative numbers. The operator “>>” uses the sign bit (left most bit) to fill the trailing positions after shift. If the number is negative, then 1 is us...
The following program demonstrates the bitwise operator assignments: publicclassMain {publicstaticvoidmain(String args[]) {inta = 1;intb = 2;intc = 3; a |= 2; b >>= 2; c <<= 2; a ^= c; System.out.println("a = "+ a); ...
