Question

I have a simple if statement that doesn’t seem to work. I’m out of ideas. I don’t understand why my logic is wrong.

String a = "bf";

if (a.compareTo("bf"))
{
    // do this
}

I’m getting a redline under the compareTo statement.

Type mismatch: cannot convert from int to boolean

Answer 1

compareTo method returns int value. so do as

if (a.compareTo("bf") == 0)      
{
    //
} 

(or)

use .equals method

if (a.equals("bf"))

{
// do this
}
