Looping check in Java -

can guide me on how looping compare data using java?

example: have lot of section 1 30 each time need take 2 section compare data (a, a) or not?

i need compare sec1, sec2 if data (a,a) add 1 output continue compare next section sec2, sec3 , on...

sec1    sec2    b sec3    c sec4    sec5    e sec6    sec7    . . . . . . 

i assume sec1,sec2 string in array.

char [] sections =  {'a','a','b','a','a','b','b','a','a','b'}; int count = 0; for(int = 0; < sections.length - 1; i++) {    if(sections[i] == 'a' && sections[i+1] == 'a')//compare want    {      count++;    } } system.out.println(count); 

edit

try {  string query = "select * emp;*;  resultset rs = stmt.executequery(query);   while(rs.next())      {       string []sections = new string[30];       for(int = 0; < 30; i++)       {       sections[i] = rs.getstring(i+1);       }      //now add checking logic here...      }     } catch(exception e) {  e.printstacktrace(); }
