You might think that you could copy a long variable into an int variable like this:
Solaris > cat prog10.java
public class prog10
{
public static void main (String args[])
{
int a;
long b = 100;
a = b;
System.out.println ("a = " + a);
System.out.println ("b = " + b);
}
}

… but you get a compilation error if you try:
Solaris > javac prog10.java
prog10.java:7: possible loss of precision
found : long
required: int
a = b;
^
1 error

You have to do it like this instead:
Solaris > cat prog11.java
public class prog11
{
public static void main (String args[])
{
int a;
long b = 100;
a = (int) b;
System.out.println ("a = " + a);
System.out.println ("b = " + b);
}
}
Solaris > javac prog11.java
Solaris > java prog11
a = 100
b = 100
