visual basic 2008 barcode generator Operators in Java
Operators Making Quick Response Code In Java Using Barcode creator for Java Control to generate, create QR Code JIS X 0510 image in Java applications. QR Code JIS X 0510 Recognizer In Java Using Barcode decoder for Java Control to read, scan read, scan image in Java applications. Two general types of operators are available in Java: binary operators and unary operators A binary operator requires two operands, such as the addition operator used Bar Code Maker In Java Using Barcode generation for Java Control to generate, create barcode image in Java applications. Decoding Bar Code In Java Using Barcode reader for Java Control to read, scan read, scan image in Java applications. Java Demystified
Generate QR Code In C#.NET Using Barcode drawer for Visual Studio .NET Control to generate, create QR Code ISO/IEC18004 image in .NET framework applications. QR Code 2d Barcode Printer In .NET Using Barcode maker for ASP.NET Control to generate, create Denso QR Bar Code image in ASP.NET applications. in previous examples in this chapter A unary operator requires one operand For example, the incremental operator (++), which you ll learn about later in this chapter, is a unary operator because it increments the value of an operand That is, it adds one to the value of the operand Operators are also organized into the following four groups: Denso QR Bar Code Printer In Visual Studio .NET Using Barcode encoder for VS .NET Control to generate, create QRCode image in Visual Studio .NET applications. Generating QR Code 2d Barcode In Visual Basic .NET Using Barcode printer for .NET Control to generate, create QR image in VS .NET applications. Arithmetic operators Relational operators Logical operators Bitwise operators
EAN13 Drawer In Java Using Barcode printer for Java Control to generate, create GS1  13 image in Java applications. EAN / UCC  13 Creator In Java Using Barcode encoder for Java Control to generate, create EAN128 image in Java applications. Arithmetic Operators
GS1 DataBar Truncated Generation In Java Using Barcode generation for Java Control to generate, create GS1 DataBar Limited image in Java applications. Barcode Printer In Java Using Barcode creation for Java Control to generate, create bar code image in Java applications. Arithmetic operators perform arithmetic operations Table 32 contains a list of arithmetic operators You are already familiar with many of these operators because they are the same operators you use everyday to perform arithmetic However, you ll notice a few that are unusual, so we ll take a close look at those in this section Print Leitcode In Java Using Barcode drawer for Java Control to generate, create Leitcode image in Java applications. Generate Data Matrix In None Using Barcode generation for Office Excel Control to generate, create Data Matrix 2d barcode image in Microsoft Excel applications. Operation Addition Subtraction and unary minus Multiplication Division Modulus Addition assignment Subtraction assignment Multiplication assignment Division assignment Modulus assignment Increment Decrement Barcode Creation In ObjectiveC Using Barcode drawer for iPad Control to generate, create barcode image in iPad applications.

CHAPTER 3 Expressions and Statements
Modulus Operator
The modulus operator is probably the first operator that catches your eye as being strange It looks as if it should return the percentage of an operand because the symbol for the modulus operator is a percentage symbol However, the modulus operator has nothing to do with percentage Instead, the modulus operator returns the remainder of the division of two operands This sounds confusing, so let s go directly to an example and see how the modulus operator works Run the following example and you ll see modulus: 4 displayed on the screen (4 is the remainder of 14 / 5) class Demo { public static void main (String args[]) { Systemoutprintln ("modulus: " + 14%5); } } Assignment Operator
The assignment operator (=) is probably one of the most misleading of all the operators because the symbol for the assignment operator is commonly used to express equality That is, two values are the same However, the assignment operator in Java tells Java to copy the value of the right operand and place it in the left operand This is illustrated in the next example, where the assignment operator in the first statement within the main() method tells Java to copy the value 5 (right operand) to the variable a (left operand): class Demo { public static void main (String args[]) { int a = 5; Systemoutprintln ("assignment operator: " + a); } } There is a tendency to say a equals 5, but that s not what is happening here Instead, we should say a is assigned the value 5 Later in this chapter, you ll learn about the relational equivalent operator (==), which is used to determine whether two operands are equal Combined Assignment Operator
You ll notice several strangelooking arithmetical operators in Table 32 that seem to use two operator symbols, such as += These operators combine two operations Java Demystified
into one operation Notice that the first operator symbol is an arithmetical operator The second operator symbol is the assignment operator Here s how this works: First, Java performs the operation specified by the first operator using the operand on the left and right of the operator The result is then assigned to the left operand The next example illustrates how each of these combined operators works The first statement assigns the value 5 to variable a, which is then displayed on the screen Next, the += operator is used First, Java adds 5 to the value stored in variable a Remember that the variable a represents the value 5 The sum of these values is 10 Next, Java assigns the sum to the left operand, which is variable a The new value of variable a is 10 See if you can determine what happens when the other statements are executed in this example and then run the example to check your answers: class Demo { public static void main (String args[]) { int a = 5; Systemoutprintln ("a = 5: " + a); a += 5; Systemoutprintln ("a += 5: " + a); a = 5; Systemoutprintln ("a = 5: " + a); a *= 2; Systemoutprintln ("a *= 2: " + a); a /= 5; Systemoutprintln ("a /= 5: " + a); a %=5; Systemoutprintln ("a %= 5: " + a); } }
