Java shift operators and assignment operators __java programming experience

A. Shift operatorThe shift operator is also for the binary "bit", which mainly includes the left shift operator (<<), the right shift operator (>>>), and the signed right shift operator (>>). Where: The left-shift operator is represented by "<<", which is the object to the left of the operator, the number of digits to the right of the left operator, and the low 0. In fact, to move n bit to the left, it is equivalent to multiply by 2 n times. The right shift operator, represented by the symbol ">>>", is the specified number of digits to the right of the object to the left of the operator, and at the top of 0, in fact, the right n bit, which is equal to the n-th side of the 2. The signed right shift operator is represented by the symbol ">>", which is the operand to the left of the operator, and the specified number of digits to the right of the operator. If it is a positive number, fill 0 in the high, or 1 in the high position if it is negative.
public class data17{
public static void Main (string[] args) {
int a=2; int b=2;
int x=16; int y=2;
int m=16;    int n=2;    int p=-16; int q=2;

The result of System.out.println ("A shift is:" + (a<<b));
SYSTEM.OUT.PRINTLN ("The result of the x shift is:" + (x>>>y));
System.out.println ("M's shift Result:" + (m>>n));
System.out.println ("P's shift Result:" + (P&GT;&GT;Q));
}
}

Run Result:
The result of a shift is: 8
The results of the x shift are: 4
Shift result of M: 4
Shift result of P:-4 two. Assignment operatorAn assignment is a value assigned to a variable, and the assignment operator acts as the assignment, but the simplest assignment operator is "=".

There are, of course, many other assignment operators besides "=". There are "+ =", "=", "*=", "/=", "%=", ">>=", ">>>=", "<<=", "&=", "|=", "^=". Here's a simple example.

public class data20{
public static void Main (string[] args) {
int a=5;
int b=2;
System.out.println ("A+=b Value:" + (a+=b));
System.out.println ("A-=b Value:" + (a-=b));
System.out.println ("A*=b Value:" + (a*=b));
System.out.println ("A/=b Value:" + (a/=b));
System.out.println ("A%=b Value:" + (a%=b));
System.out.println ("A>>=b Value:" + (a>>=b));
System.out.println ("A>>>=b Value:" + (a>>>=b));
System.out.println ("A<<=b Value:" + (a<<=b));
System.out.println ("A&=b Value:" + (a&=b));
System.out.println ("A|=b Value:" + (a|=b));
System.out.println ("A^=b Value:" + (a^=b));
}
}

Output results:
"A+=b" is a=a+b=7;
"A-=b" is a=a-b=7-2=5;
"A*=b" is a=a*b=5*2=10;
"A/=b" is a=a/b=10/2=5;
"A%=b" is a=a%b=5%2=1;
"A>>=b" is a=a>>b=0;.
"A>>>=b" is a=a>>>b=0;.
"A<<=b" is a=a<<b=0;.
"A&=b" is a=a&b=0;.
"A|=b" is a=a|b=2;
"A^=b" is a=a^b=0;
