java - stop for loop when get a specific value -

-

i have loop retrives database names .. want when got specific name stop loop , out of it..

tried didn't work :

for (int = 0; < member .length(); i++) {      jsonobject c = member .getjsonobject(i);      // storing each json item in variable     string username = c.getstring(tag_username);     s1=inputname.gettext().tostring();     if (username.equals(s1)){          suc=1;         return null;     }     else {          suc=0;     } }

also tried break; didn't work either.

how ?

update

this code working fine, found mistake in part of code.

try do ... while loop

int = 0;  {   jsonobject c = member.getjsonobject(i);   string username = c.getstring(tag_username);    i++; } while(!username.equals(inputname.gettext().tostring() && i<member.length());

this loop ends, when username equal inputname or when end of list reached.

i'm trying plot frequency characteristic equation using ezplot, matlab gives following warning, "contour not rendered non-finite zdata". have used command plot frequency equations warning , plot display empty , not change axis range well. can please help. appreciated. here's code i'm using. % transfer matrix case-i, thin rotor clear all; clc; ei = 1626; l = 0.15; m = 0.44108; = 2.178*10^-4; i_p = 2.205*10^-5; itr = 0.24; i_pr = 0.479; syms p n; f = [1 l*1i l^2/(2*ei)*1i l^3/(6*ei); 0 1 l/ei -l^2/(2*ei)*1i; 0 0 1 -l*1i; 0 0 0 l]; p = [ 1 0 0 0; 0 1 0 0; 0 -it*p^2+i_p*n*p 1 0; -m*p^2 0 0 1]; p_r = [1 0 0 0; 0 1 0 0; 0 -itr*p^2+i_pr*n*p 1 0; -m*p^2 0 0 1]; = f*p*f*p*f*p*f; b = p_r*f*p*f*p*f; r = a(1,2)/a(1,4); a12_p = 0; a22_p = a(2,2)-r*a(2,4); a32_p = a(3,2)-r*a(3,4); a42_p = a(4,2)-r*a(4,4); ap(2,2) = a22_p; ap(3,2) = a32_p; ap(4,2) = a42_p; ap(4,4) = 1; c = b*ap; m = [c(3,2) c(3,4); c(4,2) c(4,...
