Assigning string variable inside for loop

[Gopu Akraju]

Hi,

I have initially decalred string variables as follow:

And trying to assign the data inside a for loop as below:

private String lib1,lib2,lib3,lib4,lib5,lib6,lib7,lib8;

for(int i=0;i<this.lan.length;i++){
            
            lib[i] = this.lan[i-1].toString();
            
            System.out.println( "LIB:"+ lib[i]);
          
                    
   }

But I always get error inside for loop (line 3 and 4).
Thanks in advance.

Well, what does the error message say?

Hi Simon,

error says "can not find symbol lib"

Well... did you declare a variable name "lib"?

Hi Henry,
I have declared them as in line 1.

private String lib1,lib2,lib3,lib4,lib5,lib6,lib7,lib8; 

I want to loop these variables without writing like

lib1 = this.lan[0].toString();
lib2 = this.lan[1].toString();
lib3 = this.lan[2].toString();
lib4 = this.lan[3].toString();
..

I don't get any errors in the above lines. Where as I am trying do this inside a for loop.

I think you need to brush up on array variables. Declaring eight different variables whose name happen to start with "lib", is not the same as declaring a "lib" array variable.

Thanks. Henry. I have changed my code as suggested.
