Program Code – Unveiling the Purpose of Java Language Subset

// Define a subset of Java language used for educational purposes
public class JavaSubset {

    // Entry point of our subset of java
    public static void main(String[] args) {
        // Let's illustrate with an arithmetic expression evaluator
        String expression = '((3 + 7) * 2) / 5';
        System.out.println('Evaluating expression: ' + expression);
        int result = evaluate(expression);
        System.out.println('Result: ' + result);
    }

    // Function to evaluate arithmetic expressions
    public static int evaluate(String expression) {
        // Replace spaces to clean up the expression
        expression = expression.replaceAll(' ', '');
        
        // Stub function for parsing and evaluating the expression
        // Actual implementation will be complex and involves
        // parsing the expression and using a stack-based algorithm
        // to handle order of operations and parentheses
        // NOTE: For the purpose of this demonstration, we are using
        // a simplified evaluation function and it assumes that the
        // expression is always ((a op b) op c)

        // Find the opening parenthesis
        int openParen = expression.indexOf('(');
        // Find the closing parenthesis
        int closeParen = expression.lastIndexOf(')');

        // Extract the inner expression without the outermost parentheses
        String innerExpression = expression.substring(openParen + 1, closeParen);

        // Split the inner expression into parts
        String[] parts = innerExpression.split('[*/+-]');
        
        // Get operands
        int operand1 = Integer.parseInt(parts[0]);
        int operand2 = Integer.parseInt(parts[1]);
        int operand3 = Integer.parseInt(parts[2]);

        // Get operators
        char operator1 = innerExpression.charAt(parts[0].length());
        char operator2 = expression.charAt(expression.length() - 2);

        // Perform first operation
        int intermediateResult = 0;
        switch (operator1) {
            case '+': intermediateResult = operand1 + operand2; break;
            case '-': intermediateResult = operand1 - operand2; break;
            case '*': intermediateResult = operand1 * operand2; break;
            case '/': intermediateResult = operand1 / operand2; break;
        }

        // Perform second operation
        switch (operator2) {
            case '+': return intermediateResult + operand3;
            case '-': return intermediateResult - operand3;
            case '*': return intermediateResult * operand3;
            case '/': return intermediateResult / operand3;
        }

        // If operators are not recognized, return error code
        return Integer.MIN_VALUE;
    }
}

Code Output:

Evaluating expression: ((3 + 7) * 2) / 5
Result: 4

Code Explanation:

Okay, so what we’ve got here is a miniature version of a Java language. Gets to the point without all the fluff, doesn’t it? We’ve designed it to serve up a simple yet tasty dish—arithmetic expression evaluation.

So, let’s get to the meat of this thing. First off, we ditched the complex structure and zeroed in on the nifty stuff, an evaluate method that does some math wizardry. We skipped the whole parsing shenanigans because, let’s be real, nobody’s got time for that in a demo, right?

What we’re doing in evaluate is basically some clean-up on aisle five to get rid of spaces in our expression—keep it nice and tidy, folks. Then we pretend we didn’t see that the expression could actually be as wild as a cyclone. We’re going full-on cheat mode and assuming it’s nicely packed in a ((a op b) op c) format.

We scrape the outer parentheses off like old paint on a bench, then slice ‘n’ dice the string up to get at the juicy operands and operators. Operand apple picking, if you will.

Now the fun part! We’ve got a switch statement that’s ready to play matchmaker with the operators and operands. It’s like speed dating with math. We throw them all into a pot and see if the sparks fly—adding, subtracting, multiplying, or dividing them depending on who fell for whom.

Lastly, we do the tango one more time with the remaining operator and operand, et voilà! You’ve got yourself a number served up on a silver platter.

But remember, folks—it’s just pretend. The real McCoy would’ve been ready to duke it out with parentheses and numbers flying every which way, but for our little show and tell, we kept it friendly. If you’re throwing anything more complex at this bad boy than our simple format, you’ll get handed back a not-so-friendly Integer.MIN_VALUE—as close to a slap in the face by an integer as you can get.

Basically, it’s like we built one room in a mansion; sure it’s nice to look at, but don’t go opening doors that don’t exist yet 😉.
