How can I declare variable sequentially

Question

public static void main(String[] args){
    ListNode node1 = new ListNode(4);
    ListNode node2 = new ListNode(5);
    ListNode node3 = new ListNode(2);
    ListNode node4 = new ListNode(21);
    ListNode node5 = new ListNode(43);
    ListNode node6 = new ListNode(52);
    ListNode node7 = new ListNode(12);
   }

I want to declare variables sequentially using 'for' or 'while' syntax in JAVA.

In C, I know that there is a way of declaring variables sequentially using MACRO

But, In java, How can I do this?

_declare_ or _define_? What do you mean? – too honest for this site Sep 06 '15 at 13:50 — too honest for this site, Sep 06 '15 at 13:50

You can create an array of Objects like this by using a for loop:

ListNode[] node = new ListNode[7];
for(int i = 0; i<7; i++) {
    //scan a value you want to pass
    node[i] = new ListNode(valueyouwanttopass);
}

or by using a while loop as shown below:

ListNode[] node = new ListNode[7];
int i = 0;
while(i<7) {
    //scan a value you want to pass
    node[i] = new ListNode(valueyouwanttopass);
    i++;
}
