平等および関係演算子

例

次の例は、Dartで等値演算子と関係演算子を使用する方法を示しています-

void main() {
   var num1 = 5;
   var num2 = 9;
   var res = num1>num2;
   print('num1 greater than num2 ::  ' +res.toString());

   res = num1<num2;
   print('num1 lesser than  num2 ::  ' +res.toString());

   res = num1 >= num2;
   print('num1 greater than or equal to num2 ::  ' +res.toString());

   res = num1 <= num2;
   print('num1 lesser than or equal to num2  ::  ' +res.toString());

   res = num1 != num2;
   print('num1 not equal to num2 ::  ' +res.toString());

   res = num1 == num2;
   print('num1 equal to num2 ::  ' +res.toString());
}

次の output が生成されます-

num1 greater than num2 ::  false
num1 lesser than num2 ::  true
num1 greater than or equal to num2 ::  false
num1 lesser than or equal to num2  ::  true
num1 not equal to num2 ::  true
num1 equal to num2 ::  false
