arithmetic expressions Example
The variable i is initialized and its value is used to assign values to the variable j.Each of the assignments to j has an arithmetic expression to the right of the assignment operator =.
An arithmetic expression is evaluated during the run to yield a value.

class ArithmeticExpressionsExample1 {
public static void main(String[] args) {
int i = 13, j;
j = i + 3;
j = i - 3;
j = i * 2;
j = i / 3;
j = i % 4;
}
}
9-17 By running the program you will see the results of the arithmetic expressions and their assignment to j
7 Variable i is initialized with the value 13. The operator = is the assignment operator. We say the variable is assigned a value.
The variable j is declared, that is it is made known to the compiler but it is not assigned a value yet.
9 The operator + is the addition operator.
The variable j is assigned the value 16 that is the sum of the value of i and 3.
11 The operator - is the subtraction operator.
The variable j is assigned a value 10 that is the value of i minus 3.
13 The operator * is the multiplication operator.
The variable j is assigned a value 26 that is the value of i multiplied by 2.
15 The operator / is the division operator.
The variable j is assigned a value 4 that is the value of i divided by 3. Division of integers can result in truncation i.e. any remainder is discarded.
17 The operator % is the remainder operator.
The variable j is assigned a value 1 that is the remainder of the value of i divided by 4.
