Identify the false statement.

a. when you perform arithmetic operations with operands of unlike types, you must make an explicit conversion to a unifying type.
b. you can explicitly override the unifying type imposed by java by performing a type cast; type casting forces a value of one data type to be used as a value of another type.
c. summing a double, int, and float results in a double.

a. When you perform arithmetic operations with operands of unlike types, you must make an explicit conversion to a unifying type.

Explanation:

The above written statement is false because when we perform arithmetic operations with operands of unlike types we don't need to an explicit conversion because the compiler does that.The compiler automatically applies the suitable conversion conversion of data types resulting in reduction in our work.
