Chapter 3 java
The document discusses different types of operators in Java including arithmetic, relational, bitwise, logical, assignment, and miscellaneous operators. It provides examples of using arithmetic operators like addition and subtraction on integer variables and using relational operators to compare values. Logical operators are described as evaluating Boolean expressions. Assignment operators are listed as supporting operations like assignment equal. The miscellaneous ternary operator is explained as evaluating a condition and assigning a value based on the result. Finally, operator precedence is covered as affecting how expressions are evaluated based on which operators have higher precedence over others.

- 2. Operators Java provides arich set of operators to manipulate variables. We can divide all the Java operators into the following groups: • Arithmetic Operators • Relational Operators • Bitwise Operators • Logical Operators • Assignment Operators • Misc Operators
- 3. Arithmetic operator Arithmetic operatorsare used in mathematical expressions in the same way that they are used in algebra. The following table lists the arithmetic operators: Assume integer variable A holds 10 and variable B holds 20, then:
- 4.
- 5.
- 6. Relational Operator There arefollowing relational operators supported by Java language Assume variable A holds 10 and variable B holds 20, then:
- 8. Logical Operator The followingtable lists the logical operators: Assume Boolean variables A holds true and variable B holds false, then:
- 10. Assignment There are followingassignment operators supported by Java language:
- 11.
- 12.
- 13. Miscellaneous operator Conditional Operator( ? : ): Conditional operator is also known as the ternary operator. This operator consists of three operands and is used to evaluate Boolean expressions. The goal of the operator is to decide which value should be assigned to the variable. The operator is written as: variable x = (expression) ? value if true : value if false
- 14. Precedence of JavaOperator Operator precedence determines the grouping of terms in an expression. This affects how an expression is evaluated. Certain operators have higher precedence than others; for example, the multiplication operator has higher precedence than the addition operator:

- 16.
