break and contine in blocks

[Lokanadham Nalla]

--------------------------------------
1)

block:
{
break block;
}
--------------------------------------
2)

block:
{
continue block;
}
--------------------------------------
1 is valid and 2 is invalid,

Can we apply break to block statements? Is it valid?

[abhishek chauhan]

a label break statement can be used to terminate any labeled statements that contains break statement .. this could be a normal block also where as the continue statement can only be applied to the loops

[Alangudi Balaji Navaneethan]

break statement is used in loops and in switch statements normally.

When used in switch case, control come out of the switch after executing break statement. Continue statement cannot be used with swith ... case statements.

continue statement takes the control to the test portion of the loop after executing itself. Then the loop will continue its body or not based on the test result.

[Arulkumar Gopalan]

continue can indirectly act as a break also... check the code below.

 
class Loop
{
 
public static void main(String ss[])
{
 
System.out.println("compiled & executed => arul");
 
AmOutLoop:
for(int iO=0;iO<3;iO++)
AmInLoop:
for(int i=0;i<4;i++)
{
System.out.println("------");
System.out.println("First print i = "+i);
if(i==2) /*break AmInLoop;*/ continue AmOutLoop; /*break AmOutLoop; continue AmInLoop;*/
System.out.println("Second print i = "+i);
}
 
System.out.println("compiled & executed => Switch");
 
int i=1;
switch(i)
{
case 0:
System.out.println("case 0");
case 1:
System.out.println("case 1");
break; //continue can not be applied
case 2:
System.out.println("case 2");
default:
System.out.println("default");
}
 

}
}
