PLS HELP.

Have most of my code but keeps having a error.

Heres my code for MyArrayList.java:

import java.util.NoSuchElementException;

public class MyArrayList implements MyList $\{$

private int currentCapacity $=8$;

private int size $=0$;

private Object$[]$ storage $=$ new Object$[$currentCapacity$]$;

public void append$($Object o$)\{$

if $($size $==$ currentCapacity$)\{$

makeCapacity$($currentCapacity $*2)$;

$\}$

storage$[$size$++]=$ o;

$\}$

public void insertAt$($int index, Object o$)\{$

if $($index $<mtext></mtext><mn>0</mn><mtext></mtext><mi>|</mi><mi>|</mi>$ index $>$ size$)\{$

throw new NoSuchElementException$("$Index out of bounds"$)$;

$\}$

if $($size $==$ currentCapacity$)\{$

makeCapacity$($currentCapacity $*2)$;

$\}$

for $($int i $=$ size; i $>$ index; i$--)\{$

storage$[$i$]=$ storage$[$i $-1]$;

$\}$

storage$[$index$]=$ o;

size$++$;

$\}$

@Override

public void removeAt$($int index$)\{$

if $($index $<mtext></mtext><mn>0</mn><mtext></mtext><mi>|</mi><mi>|</mi>$ index $>=$ size$)\{$

throw new NoSuchElementException$("$Index out of bounds"$)$;

$\}$

for $($int i $=$ index; i $$ size $-1$; i$++)\{$

$\}$

size$--$;

return storage$[$index$]$;

return;
