代替
todos[pos + 1] = todos[pos];
您应该使用
todos[pos] = todos[pos + 1];
这是工作代码:
public static boolean deleteTask() {
boolean removed = false;
for (int pos = 0; pos < todos.length; pos++) {
if (todos[pos].equals(titel)) {
todos[pos] = null;
removed = true;
}
if (removed && pos < todos.length - 1) {
// swap the string with the next one
// you can't do this with the last
// element because [pos + 1] will
// throw an indexoutofbounds exception
todos[pos] = todos[pos + 1];
} else if (removed && pos == todos.length - 1) {
// here you can swap the last one with null
todos[pos] = null;
}
}
return removed;
}
