Containers...replacing two chars with a string

Question

public static char[] translate(String string)
Scanner sc=new Scanner(string);
int x=0;
char output[]=string.toCharArray();
for(int i=0; i<output.length; i++)
if (output=='[')
if(output[i++]=='C')
output[].remove(i);
output[].remove(i++);
output[].insert(output, i, 6);
output[].fill(output, i, i+6, "char[]");
return output;

Answer 1

i apologize. i am unable to edit the code.
i want to find and replace two contiguous chars, '[' and 'C' with the string "char[]" ...I have just found that remove, insert and fill do not exist in the char array...How can I edit this function to return a string after it's been edited?
the code i posted returns compile errors: Firstclass.java:163: class expected
output[].remove(i);

Firstclass.java:163: not a statement
output[].remove(i);
