You nailed both!
a.
public void printNotes(){
Note n=new Note();
for（int i=0;i<n.size();i++){
System.out.println((i+1)+". "n.getNote(i));
}
}
This is Jerry
Nice try Jerry. You started a new Note object, as a matter of fact, you only need to print out the noteList.
b.
public void removeNotes(String str){
Note n=new Notes();
for（int i=0;i<n.size();i++){
for(int j=0;j<n.get(i).length;j++){
for(int r=0;r<n.get(i).length;r++){
if(n.get(i).substring(j,r)==str){
n.remove(i);
}
}
}
}
}
Nice flow. Again, the instance variable noteList has the list of notes to remove from.
There is a method named "indexOf(String s)", it can be used to see if a string contains another string.
