Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

- Write in Java.
(Convert infix to postfix)
Note:
- Postfix notation is a way of writing expression without using parentheses. For example, the expression ( 11 + 12 ) * 13 would be written as 11 12 + 13 *
- Assume that ALWAYS there is a space between operands and operators in the input expression.
- Use two stacks, one to store the operands and one to store the operators.
- Your program only accpets following operators :
- ( )
- +
- -
- /
- *
Write a method to converts an infix expression into a postfix expression using the following method:
String infixToPostfix(String expression)
For example, the method should convert the infix expression
( 13 + 25 ) * 34 to 13 25 + 34 *
and
20 * ( 10 + 30 ) to 20 10 30 + *.

import java.util.*;

class InfixToPostfix {
public String infixToPostfix(String expression) {
}
}
class DriverMain {
public static void main(String args[]) {

InfixToPostfix postfix = new InfixToPostfix();
try {
System.out.println(postfix.infixToPostfix(input.nextLine()));
}
catch (Exception ex) {
System.out.println("Wrong expression");
