Sometimes i used to use if branch, sometimes AND operand. But i feel they are both same. What their different actually? Any there example case which i must use that ONE only?
For example:
//Defining variable
a=2
b=3
if(a==2){
if(b==3){
println("OK");
}
}
It's equal with
if (a==2 && b==3){
println("OK");
}
You might use the first doubly-nested if condition when the inner if had an else branch, e.g.
if (a == 2) {
if (b == 3) {
println("OK");
}
else {
println("not OK")
}
}
If you don't have this requirement, then the second more concise version is probably what most would choose to use:
if (a == 2 && b == 3) {
println("OK");
}
