A. Review 1) HW check 2) Kahoot! B. H. What are Javadoc Comments? What do @param and @return do? (@throws is useful but won't be tested.)
What does short circuit evaluation of logical operators do?
I. Which operation has the lowest precedence?
J. What is the difference between nested ifs and sequential ifs? What about nested loops and sequential loops?
K. How to call static methods and pass arguments?
public void printNotes(){
for(int i=0;i<noteList.size();i++){
System.out.println(((i+1)+". ")+noteList.get(i));
}
}
public void removeNotes(String str){
int totalChar = 0;
for(int i=0;i<noteList.size();i++){
for(j=0;j<noteList.get(i).length()-str.length();j++){
if(noteList.get(i).substring(j,j+str.length()).compareTo(str)==0){
noteList.remove(i);
}
}
}
}
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.
