说明二进制字面量使用的Java程序

二进制字面量是用 0 和 1（二进制数字）表示的数字。 Java允许您在二进制数系统中表示整数类型（byte、short、int 和 long）。要指定二进制字面量，请将前缀 0b 或 0B 添加到整数值。因此，我们可以通过将二进制数字分配给变量来表示程序中的二进制数字，并且这些变量在执行程序后的输出将是十进制数字。

在Java中实现二进制字面量：

我们可以探索在Java编程语言中实现和使用二进制字面量的方法。第一个和后面的Java程序是实现不同类型的二进制字面量的示例。如上所述， Java允许我们表达 byte、short、int 和 long 类型的二进制字面量。

Java

// Java Program to Illustrate Use of Binary Literals
public class GFG {
    public static void main(String[] args)
    {
        // Byte type Binary Literal
        byte a1 = 0b011;
  
        // The b can be lower or upper case
        byte a2 = 0B101;
        System.out.println("Binary Literal in Byte----->");
        System.out.println("a1 = " + a1 + ", "
                           + "a2 = " + a2);
  
        // Short type Binary Literal
        short b1 = 0b101;
  
        // The b can be lower or upper case
        short b2 = 0B111;
        System.out.println("Binary Literal in Short----->");
        System.out.println("b1 = " + b1 + ", "
                           + "b2 = " + b2);
  
        // Int type Binary literal
        int c1 = 0b011;
  
        // The b can be lower or upper case
        int c2 = 0B111;
        System.out.println(
            "Binary Literal in Integer----->");
        System.out.println("c1 = " + c1 + ", "
                           + "c2 = " + c2);
  
        // Long type Binary literal
        long d1 = 0b0000011111100011;
  
        // The b can be lower or upper case
        long d2 = 0B0000011111100001;
  
        System.out.println("Binary Literal in Long----->");
        System.out.println("d1 = " + d1 + ", "
                           + "d2 = " + d2);
    }
}

Java

// Java Program to Illustrate Use of Binary Literals
public class GFG {
    public static void main(String[] args)
    {
        byte n1 = 3; // Decimal number
        byte n2 = 0b011; // Binary of 5
        byte n3 = -0b111; // Negative binary number
        byte n4 = 0b1101;
  
        System.out.println("n1 = " + n1);
        System.out.println("n2 = " + n2);
        System.out.println("n3 = " + n3);
        System.out.println("n4 = " + n4);
  
        // Checking if the decimal and binary digits are
        // equal
        System.out.println("is n1 and n2 equal: "
                           + (n1 == n2));
        // Adding 1 to a binary digit
        System.out.println("n2 + 1 = " + (n2 + 1));
  
        // Adding 1 to a negative binary digit
        System.out.println("n3 + 1 = " + (n3 + 1));
  
        // Multiplying 2 with a binary digit
        System.out.println("n4 x 2 = " + (n4 * 2));
    }
}

输出

Binary Literal in Byte----->
a1 = 3, a2 = 5
Binary Literal in Short----->
b1 = 5, b2 = 7
Binary Literal in Integer----->
c1 = 3, c2 = 7
Binary Literal in Long----->
d1 = 2019, d2 = 2017

在Java中，运算符可用于二进制字面量以执行操作。以下Java程序是对二进制字面量实现不同数学和比较运算的示例。这些对二进制字面量的操作的结果是十进制数字。

// Java Program to Illustrate Use of Binary Literals
public class GFG {
    public static void main(String[] args)
    {
        byte n1 = 3; // Decimal number
        byte n2 = 0b011; // Binary of 5
        byte n3 = -0b111; // Negative binary number
        byte n4 = 0b1101;
  
        System.out.println("n1 = " + n1);
        System.out.println("n2 = " + n2);
        System.out.println("n3 = " + n3);
        System.out.println("n4 = " + n4);
  
        // Checking if the decimal and binary digits are
        // equal
        System.out.println("is n1 and n2 equal: "
                           + (n1 == n2));
        // Adding 1 to a binary digit
        System.out.println("n2 + 1 = " + (n2 + 1));
  
        // Adding 1 to a negative binary digit
        System.out.println("n3 + 1 = " + (n3 + 1));
  
        // Multiplying 2 with a binary digit
        System.out.println("n4 x 2 = " + (n4 * 2));
    }
}

输出

n1 = 3
n2 = 3
n3 = -7
n4 = 13
is n1 and n2 equal: true
n2 + 1 = 4
n3 + 1 = -6
n4 x 2 = 26
