写了一段判断奇偶性的Java代码，编译能行就是会出现那种情况(最后)求助🆘🆘package chapter1;public class AA { public static void main(String[] args) { A T=new A(); if(T.t(4)){ System.out.println("偶数"); } else System.out.println("奇数"); }}class A{public boolean t (int num1){ if (num1%2==0) return true; else return false;} }Exception in thread "main" java.lang.NoSuchMethodError: chapter1.test.t(I)Z at chapter1.AA.main(AA.java:7)
