The length of list is five but I want a length of list 150 [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. 开发者_开发问答 Closed 11 years ago.

static final ArrayList<HashMap<String,String>> arraylistobject = new ArrayList<HashMap<String,String>>();
    private void populateList() {
        HashMap<String,String> temp = new HashMap<String,String>();
        temp.put("pen","MONT Blanc");
        temp.put("price", "200 rs");
        arraylistobject.add(temp);
        HashMap<String,String> temp1 = new HashMap<String,String>();
        temp1.put("pen","Gucci");
        temp1.put("price", "300 rs");
        arraylistobject.add(temp1);
        HashMap<String,String> temp2 = new HashMap<String,String>();
        temp2.put("pen","Parker");
        temp2.put("price", "400 rs");
        arraylistobject.add(temp2);
        HashMap<String,String> temp3 = new HashMap<String,String>();
        temp3.put("pen","Sailor");
        temp3.put("price", "500 rs");
        arraylistobject.add(temp3);
        HashMap<String,String> temp4 = new HashMap<String,String>();
        temp4.put("pen","Porsche Design");
        temp4.put("price", "600 rs");

You can use a loop to create the HashMaps and add them to your List, but you still have to do something about those hard-coded String literals.

for(int i = 0; i < 150; i++) {
    HashMap<String,String> temp = new HashMap<String,String>();
    temp.put("pen", "MONT Blanc");
    temp.put("price", "200 rs");
    arraylistobject.add(temp);
}

You could read the values that you put in the temp map from a configuration file or a database to initialize the List, but that's a whole other issue.

You should also check out the Java Tutorials: Collections articles.

A List is meant to grow, not have a pre-initialised size. So if you want 150 as the length, you should add 150 elements to the list. Otherwise, stick to arrays.
