![]() Let's have a look at infix and postfix expressions. Before moving ahead in this section, ensure that you are friendly with the stack and its operations. The stack is used to store the operators and parenthesis to enforce the precedence Start parsing the expression from left to right. In this section, we will learn how to convert infix expression to postfix expression and postfix to infix expression through a Java program.įor performing the conversion, we use Stack data structure. Parenthesis has the highest precedence and the expression inside it must be converted first. ![]() ![]() The precedence of the operators (+, -) is lesser than the precedence of operators (*, /, %). The infix and postfix expressions can have the following operators: '+', '-', '%','*', '/' and alphabets from a to z.
