Java program using If-Else Condition

WAP :Given 2 int values, return true if one is negative and one is positive. Except if the parameter "negative" is true, then return true only if both are negative. 


public class NegativePositive {

    public static void posNeg(int a,int b, boolean neg)
    {
        if((a<0&b>0&neg==false)|(a>0&b<0&neg==false))
        {

            System.out.println(true);

        }
        else if(a<0&b<0&neg==true)
            System.out.println(true);

        else
            System.out.println(false);

    }    public static void main(String[] args) {
     
            posNeg(-5,-1,true);
    }

}
