& And && difference is & will perform on both sides, regardless of whether the establishment of the first
&& performed only one side, if the first condition is false, it will not take the second condition
, for example
public class Test2 {
public static void main(String[] args){
int i=3;
if((i++>5)&(i++<9)){
System.out.println(i);
System.out.println ( "Congratulations, the implementation of conditional statements is over!");
}
System.out.println(i);
}
}
The result is i = 5
public class Test2{
public static void main(String[] args){
int i=3;
if((i++>5)&&(i++<9)){
System.out.println(i);
System.out.println ( "Congratulations, the implementation of conditional statements is over!");
}
System.out.println(i);
}
}
The result is i = 4
|| and | are mean "or" || difference is that as long as the first condition is met, the latter condition is no longer judge, but | to judge all conditions.
Note that when they carry out operations, & represents the first two numbers are turned into binary, and then the two numbers are only 1 to 1, the other for 0
| represents the number two as long as there is a 1 is 1, others are 0
