逻辑运算符和布尔表达式还可以这样用

public class Test {
static boolean isTrue() {
System.out.println("isTrue");
return true;
}

static boolean isFalse() {
System.out.println("isFalse");
return false;
}

public static void main(String[] args) {
  if (isTrue() || isFalse()) {
   System.out.println(" || operate return true");
  }
  if (isFalse() & isTrue()) {

   System.out.println(" & operate return true");
  }
}
}
