spring validation annotation for compulsory and non-compulsory fields -

- 

     @notempty private string cname; public string getcname() {     return cname; } public void setcname(string cname) {     this.cname = cname; }  private string cdescription; public string getcdescription() {     return cdescription; } public setcdescription(string cdescription) {     if(cdescription.length()>0){     this.cdescription = cdescription;}

in above code,cname compulsory field , cdescription non-compulsory field has validated.cname working fine. want know how can validate cdescription w/o making compulsory

as per requirement can use different annotations of javax.validation http://docs.oracle.com/javaee/6/api/javax/validation/constraints/package-summary.html hibernate validation you.@notblank , @notnull , @notempty various types of annotation available in hibernate-validator jar.

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
