    //Mothly 
    double ad = 1 + mon;  
    double amt,amt_mon,amt2; 
    amt_mon = -1*((Math.log(1 - ((mon * loan_amt)/pay)))); 
    amt2 =(Math.log(ad));

    System.out.println("Number of Payments based on monthly : "+amt); 

    //Quarterly 
    ad = 1 + quarterly; 
    double amt_quart; 
    amt_quart = ((-Math.log(1 - ((quarterly * loan_amt)/pay)))); 
    amt = (amt_quart/amt2); 
    System.out.println("Number of Payments based on quarterly : "+amt); 

    //HalfYearly 
    ad = 1 + Half; 
    double amt_half; 
    amt_half = ((-Math.log(1 - ((Half * loan_amt)/pay)))); 
    amt = (amt_half/amt2); 
    System.out.println("Number of Payments based on HalfYearly : "+amt); 

    //Annually 
    ad = 1 + annual; 
    double amt_ann; 
    amt_ann = ((-Math.log(1 - ((annual * loan_amt)/pay)))); 
    amt = (amt_ann/amt2); 
    System.out.println("Number of Payments based on Annually : "+amt); 
    } 
}
