Explanation / Answer

You have the following code in your question:

else if(weeks < 0){
for (int i = 0; i < bonus[weeks].length; i++) {
  
}
}

--------------

After your edit in question:

if (weeks > 6) {
weeks = 6;
}
else if(weeks < 0){
outputBox.setText("Invalid Number");
}
reviews = Integer.parseInt(weeksWorked.getText());
  
if (reviews > 4) {
reviews = 4;
}
this.outputBox.setText("$" + bonus[weeks][reviews]);
}

Error is occuring during access to bonus[weeks][reviews].

You can correct the code in following manner:

int flag = 1; // everything is correct
weeks = Integer.parseInt(weeksWorked.getText());
if (weeks > 6) {
   weeks = 6;
}
else if(weeks < 0){
   flag = -1; // invalid number
}

reviews = Integer.parseInt(weeksWorked.getText());
if (reviews > 4) {
   reviews = 4;
}
else if (reviews < 0){
   flag = -1; // invalid number
}

if (flag == 1){
   this.outputBox.setText("$" + bonus[weeks][reviews]);
}
else{
   this.outputBox.setText("Invalid Number");
}
