GOTO FOR JAVA???

Question

I have made a small program on elipse.Heres a part of it:-

int x=input();//input is a method that uses scanner to get input as int.

if(x==1)
s.o.p("a");//s.o.p=System.out.print
else if (x==0)
s.o.p("b");
else {
s.o.p("Please enter either 0 or 1);
*Here I want "something" so as to go back to first line(int x=input()) ,so as to 'loop' again through if -else .Something known as goto in another language(I dont remember the name ,I think its C++)

Any way in which I can do it?
Alternative for goto in java??

Answer 1

You can use label like this : https://www.tutorialspoint.com/javaexamples/method_label.htm

Answer 4

int x = input ();
while (x != 0 && x != 1) {
s.o.p("please enter 1 or 0);
x = input ();
}

if (x == 1) {
s.o.p("a")
} else ( x == 0) {
s.o.p ("b");
}
