WHILE
EXAMPLE
Public class test
{
public static
void main(String args [])
{
int i=0;
while(i==5)
{
System.out.println(“hai”);
i++;
}
}
}
DO
WHILE
—This loop will
execute the code block once, before checking if the condition is true, then it
will repeat the loop as long as the condition is true.
Syntax
do {
// code block to be executed
}
while (condition);
// code block to be executed
}
while (condition);

DO
WHILE EXAMPLE
—int i
= 0;
do {
System.out.println(i);
i++;
}
while (i < 5);
do {
System.out.println(i);
i++;
}
while (i < 5);
