Setters and Getters are used to hide the implementation of fields in an object, and just provide a convenient method to save or return a value. At its most basic level you could have something like:
private double taxAmount;
public double getTaxAmount()
{
return taxAmount;
}
public void setTaxAmount(double value)
{
taxAmount = value;
}
If the implementation of the field changes then it should only be necessary to modify the setter and getter thus avoiding changes to the code in the rest of the class.

I have a requirement to fetch the details from pos transaction and use it in my application(Based on Java) for business purpose.
Please suggest best possible solution to proceed.
on discussions i found few possible solution to start are Applets or Active X . But didnt get much information on how to start with any of the above option or any other possible solution.
Any input will be really appreciated
Thanks in advance

The first thing to research is how the POS presents its data, and through what interface.

I am unable a to understand a concept. double variable and double array are declared outside the function and a function which increments the value of both is made. Values from the functions are not returned still the value of the double array gets incremented where as it is not the same case with double variable. Why ? Same with Double class
double x = 100.5;
p.m1( x );
System.out.println("" + x);
double[] xa1 = {10,20,30,40};
for (int i=0;i<4;i++){
System.out.println(xa1[i]);
}
public void m1(double a) {
a += 100;
}
public void m5(double[] x) {
for(int i=0; i < x.length; i++)
x[i] += 100;
}
OUTPUT : 100.5
110.0 120.0 130.0 140.0

'a' is an instance and it is copied when you call m1().
'x' is a reference so when 'x' is used in m5() the original, not a copy is used.
The above is a simple explanation and it is not exactly true semantically but is true conceptually. But without understanding what you are trying to understand I don't want to explain what is actually going on.

how to read large 8gb json text file in java program.
I am try with FileInputStream in java but after 2gb it's not work.

If you are trying to read all that much data into memory then it will never work. You need to read it in smaller blocks and process only the data you can hold in memory.

It is not clear what your problem is. The above would appear to be some XML formatted data, so you can use the XMLReader (Java Platform SE 7 )[^] to extract the fields from it.

The spark of current version is used FMJ library as media library,
and so the voice chatting can't progress.
If the libjitsi library replace fmj, I don't know it to be impossible.
