while - Example
public class While {
public static void main(String a[]){
int i=0;
System.out.println(
"\nbefore first while loop");
while(i<10){
System.out.print(
"" + i + ",");
i=i+1;
}
i=20;
System.out.println(
"\n\nbefore second while loop");
while(i<10){
System.out.print("" + i + ",");
i=i+1;
}
System.out.println(
"\nafter second while loop");
}
