For my given query i got the above result set, but in that result set i want reduce duplicate name with single name, cal their amout (mean subtract Debit amount from Credit)

I think have to use some sorting technique for this, i use one technique iam getting data which r duplicate and calculate them, but not getting records which without duplicate.

Iam providing what i use technique

ResultSet rs=null;
 rs=st.executeQuery("select flag,maname,sum(sum_amt) from mob1 group by flag,maname");
 while(rs.next())
 {
	FLAG[p]=rs.getString(1);
	MANAME[p]=rs.getString(2);
	AMT[p]=rs.getInt(3);
	p++;
 }
 rs=null;
 int q=0;
 int s=0;
 int s1=0;
 for(int i=0;i<p-1;i++)
 {
	String x=FLAG[i];
	String y=MANAME[i];
	int z=AMT[i];
	for(int j=i+1;j<p;j++)
	 {
		String x1=FLAG[j];
		String y1=MANAME[j];
		int z1=AMT[j];
		if((y.equals(y1)) && !(x.equals(x1)))
		 {
			if(z>z1)
			 {
				NAME[q]=y;
				CRDR[q]=x;
				SUM[q]=z-z1;
				s=s+SUM[q];
				q++;
			 }
			 else
			 {
				NAME[q]=y;
				CRDR[q]=x1;
				SUM[q]=z1-z;
				s1=s1+SUM[q];
				q++;
			 }//else
			 
		 }//if
	 }//for(j
 }//for(i

You have to add logic for "y not equal to y1" for non-duplicate values
