Java で数式を文字列として解析および評価するにはどうすればよいですか?

Interpreter interpreter = new Interpreter();
interpreter.eval("result = 5+4*(7-15)");
System.out.println(interpreter.get("result")); // Prints -14

// Import ANTLR dependencies
import org.antlr.v4.runtime.*;
import org.antlr.v4.runtime.tree.*;

// Create a char stream from the expression string
CharStream charStream = CharStreams.fromString("5+4*(7-15)");

// Generate a lexer that tokens the input
Lexer lexer = new MathLexer(charStream);

// Generate a parser that parses the tokens
Parser parser = new MathParser(new CommonTokenStream(lexer));

// Parse the expression and generate a parse tree
ParseTree tree = parser.statement();

// Perform semantic actions to evaluate the expression
SemanticListener listener = new SemanticListener();
ParseTreeWalker.DEFAULT.walk(listener, tree);

// Retrieve the result from the listener
double result = listener.getResult(); // -14
