    <p>I want to check branchList whether has same element or not, if same put branchList and tglList element separate arraylist and put that arraylist into another arraylist, </p> <p>The result I want is BranchList1 have 2 arraylist where 1st arraylist contain for element '1' and 2nd arraylist contain element '2' and TglList1 have 2 arraylist as element, but what i get is both 1st and 2nd array get same value.</p> <p>How can this be done?</p> <pre><code>ArrayList branchList = new ArrayList(); branchList.add("1"); branchList.add("1"); branchList.add("1"); branchList.add("2"); branchList.add("2"); branchList.add("2"); ArrayList tglList = new ArrayList(); tglList.add("5"); tglList.add("10"); tglList.add("20"); tglList.add("100"); tglList.add("500"); tglList.add("1000"); ArrayList newBranchList = new ArrayList(); ArrayList newTglList = new ArrayList(); ArrayList BranchList1 = new ArrayList(); ArrayList TglList1 = new ArrayList(); ArrayList abc = new ArrayList(); String checkBranch = new String(); for(int i=0;i&lt;branchList.size();i++){ String branch = branchList.get(i).toString(); if(i==0 || checkBranch.equals(branch)){ newBranchList.add(branch); newTglList.add(tglList.get(i).toString()); }else{ BranchList1.add(newBranchList); TglList1.add(newTglList); newBranchList.clear(); newTglList.clear(); newBranchList.add(branch); newTglList.add(tglList.get(i).toString()); } if(i==(branchList.size()-1)){ BranchList1.add(newBranchList); TglList1.add(newTglList); } checkBranch = branch; } } </code></pre> <p>so expected result is as below:</p> <pre><code>BranchList1 = [ [1,1,1],[2,2,2]] TglList1 = [[5,10,20],[50,100,200]] </code></pre> <p>but what I get is </p> <pre><code>BranchList1 = [ [2,2,2],[2,2,2]] TglList1 = [[50,100,200],[50,100,200]] </code></pre> <p>How can I modify the code</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
