Example​

Before​
import java.security.spec.RSAKeyGenParameterSpec;

public class RSAKeyExample {
    public void generateKey() {
        // Basic RSA key generation with 2048 bits and F4 exponent
        RSAKeyGenParameterSpec spec = new RSAKeyGenParameterSpec(2048,
            RSAKeyGenParameterSpec.F4);
    }
}
After​
import java.security.spec.RSAKeyGenParameterSpec;

public class RSAKeyExample {
    public void generateKey() {
        // Basic RSA key generation with 2048 bits and F4 exponent
        RSAKeyGenParameterSpec spec = /*~~>*/new RSAKeyGenParameterSpec(2048,
            RSAKeyGenParameterSpec.F4);
    }
}
