$1.$ Find the error in the following code do

String temp $=""$ ;

int j $=$ str$2.$length$()-1$;

for$($int i$=$j; i$>=0$; i$--)$;

$\{$temp $=$ temp $+$ str$2.$charAt$($i$)$;

System.out.println$($temp$)$;

$\}$

a$.$ No error in code

b$.$ Remove $$;$$ in for loop

c$.$ charAt$($i$)$ needs to be charAt$($j$)$

d$.$ String temp cannot be $"".$
