Although using braces is a a common practice, it is sometimes very misleading and it can take hours to figure out what is wrong.
A simple way to avoid such problems is to use the curly braces ({}) as needed to avoid ambiguity.
Below is a simple code sample that does not have braces, and hence, there are problems during compilation.
class UsingBraces
{
public static void main(String args[])
{
UsingBraces usingBraces = new UsingBraces();
usingBraces.proceed();
}
private void proceed()
{
for (int i=0;i System.out.println("i: " + i); System.out.println("i: " + 5);
//In the above line, the statement System.out.println("i: " + 5); is not part of the loop.
//If you try replacing the value 5 as i, the compiler itself throws an error indicating that the variable i cannot be identified.
}
}
/*
Expected output:
[root@mypc]# java UsingBraces
i: 0
i: 1
i: 5
