Java学习——Java运算符

位运算符

A = 0011 1100
B = 0000 1101
-----------------
A&b = 0000 1100
A | B = 0011 1101
A ^ B = 0011 0001
A << 2 = 1111 0000
A >>> 2 = 0000 1111
~A= 1100 0011

package import_test;

public class Employee {public static void main(String args[]){int a = 60;
int b = 13;
System.out.println(a | b);
System.out.println(a & b);
System.out.println(a ^ b);
System.out.println(~a);
System.out.println(a << 2);
System.out.println(a >>> 2);

}

条件运算符

public class Employee {
public static void main(String args[]){
int a = 10;
int b = 8;
String rev = a > b ? "a > b" : "a<= b";
System.out.println(rev);
}
}

a > b
