Write a program name InfixToPostfix.java that converts an infix expression entered by the user to a postfix expression. The expression may contain the following tokens: (a) Integer constants (a series of decimal digits). (b) x (representing a value to be supplied later). (c) Binary operators (+, -, *, / and %). (d) Parentheses Spaces between tokens are allowed but not required. The program will convert the expression to postfix form and display the converted expression.

Sample Output:

Enter infix expression: (x + 1) * (x 2) / 4 Converted expression: x 1 + x 2 - * 4 /

Enter infix expression: 1 2 + Error in expression!! No operator between operands. Also last token must be an operand.

Enter infix expression: 10.4 Error in expression!! Cannot accept floating point numbers. Enter infix expression: 1 ( + 2) Error in expression!! No operator between operand and left parentheses. Enter infix expression: 5 (x 2)) Error in expression!! No matching left parentheses for a right parentheses. Enter infix expression: 1 ** 2 Error in expression!! The * operator cannot be preceded by a * operator.
