Java将字符串转换为逻辑

Question

//having Java 7/8: String logic = "123 OR 345 OR 678 NAND 901";

//Should evaluate something simililar to this: 
String test1 = "abc345678opq"; String test2 = "abc123901";

boolean isCheckOk1 = test1.contains("123") || test1.contains("345") || test1.contains("678") && !test1.contains("901");

boolean isCheckOk2 = test2.contains("123") || test2.contains("345") || test2.contains("678") && !test2.contains("901");

//where isCheckOk1 will be true

//and isCheckOk2 will be false;

Is there a generic way in Java a library to achive this?

Next level:

"123 OR 345 OR 678 NAND (901 AND 902)"

Thank you!

No, but you could use regex:

This:

boolean isCheckOk1 = test1.contains("123") || test1.contains("345") || test1.contains("678") && !test1.contains("901");

can be coded as:

boolean isCheckOk1 = test1.matches("(?!.*901).*(123|345|678).*");

---

The "extra points" could be coded as:

boolean isCheckOk1 = test1.matches("(?!.*901.*902)(?!.*902.*901).*(123|345|678).*");

---

Complicated logic would become unwieldy to do in regex.
