Question
Are these Java boolean equations true or false?
!(6==6)&&(1==1);
(8<9) && (14>14);
!(8<9) || (12>14);
(1<=1);
!(7==7);
!(1==1)||(2==2)||(3==3);
(100 + 5) == (40 + 65);
(8<9) && (15>14) && (12>11);
(19<9) || !(15>14);
I'm having a hard time with these. The ! operator is throwing me off. After this I have to then create a class to check the problems. If I could get help with just the first equation, I think I will be able to do the rest.
Explanation / Answer
1)1 st equation is false because 6==6 is true and !(6==6) is false and 1==1 is true so finally false && true is false
public class Test {
public static void main(String args[])
{
if(!(6==6)&&(1==1))
{
System.out.println("true");
}
else
{
System.out.println("false");
}
}
}
(8<9) && (14>14)-false
!(8<9) || (12>14)-false
(1<=1)-true
!(7==7);-false
!(1==1)||(2==2)||(3==3) - true
(100 + 5) == (40 + 65) -true
(8<9) && (15>14) && (12>11) - true
(19<9) || !(15>14)-false
