Question

My question to java folks is, when I am comparing two strings

imageName=new String[20];    
....    
imageName[1]="img1";  
imageName[2]="img1";  

if(imageName[1]==imageName[2])  
{  
 ////  codes  
}

it works perfectly, but when I am making the string through number concatenation it’s not working

imageName=new String[20];  
int j=1,k=1;  
imageName[1]="img"+j;  
imageName[2]="img"+k;

 if(imageName[1].toString()==imageName[2].toString())     
        {  
           ////  codes  
        }  

it’s not working though the values of j and k are the same

Thanks in advance for your solution

You should use String.equals when comparing two Strings:

if (imageName[1].equals(imageName[2])
