The setParseIntegerOnly() method is a built-in method of the java.text.NumberFormat which sets whether or not numbers should be parsed as integers only.
Syntax:
public void setParseIntegerOnly(boolean val)
Parameters: The function accepts a mandatory parameter val which specifies the value to be set
Return Value: The function returns nothing, hence has a return type void.
Below is the implementation of the above function:
Program 1:
// Java program to implement// the above function import java.text.NumberFormat;import java.util.Locale;import java.util.Currency; public class Main { public static void main(String[] args) throws Exception { NumberFormat nF = NumberFormat.getNumberInstance(); System.out.println("set initially as: " + nF.isParseIntegerOnly()); // Set grouping nF.setParseIntegerOnly(false); // Print the final System.out.println("set finally as: " + nF.isParseIntegerOnly()); }} |
Output:
set initially as: false set finally as: false
Program 2:
// Java program to implement// the above function import java.text.NumberFormat;import java.util.Locale;import java.util.Currency; public class Main { public static void main(String[] args) throws Exception { NumberFormat nF = NumberFormat.getNumberInstance(); System.out.println("set initially as: " + nF.isParseIntegerOnly()); // Set grouping nF.setParseIntegerOnly(true); // Print the final System.out.println("set finally as: " + nF.isParseIntegerOnly()); }} |
Output:
set initially as: false set finally as: true
