i) break : This statement is used to transfer the execution flow outside the loop body.
int x=5,i=1;
while(i<=10)
{
System.out.println(i);
i++;
if (i==x)
break;
}
The output will be:
1
2
3
4
ii ) continue :This statement changes the flow of execution to stop the current iteration and moves to the next iteration.
int x=5,i=0;
while(i<=10)
{
++i ;
if (i==x)
continue;
else
System.out.println(i);
}
The output will be:1
2
3
4
6
7
8
9
10
