Byte類的compareTo()方法是Java中的一種內置方法,用於將給定的Byte類型對象與Byte實例調用compareTo()方法進行比較。
用法
ByteObject.compareTo(Byte a)
參數:它接受一個Byte類型的對象a作為輸入,該對象將與調用compareTo方法的Byte對象的實例進行比較。
返回值:它返回一個int值。它返回:
- 如果'a等於'b,則為0,
- 正值“ a”大於“ b”,
- 負值“ b”大於“ a”
下麵是Java中compareTo()方法的實現:
示例1:
// Java code to demonstrate
// Byte compareTo() method
class GFG {
public static void main(String[] args)
{
// creating a Byte object
Byte a = new Byte("20");
// creating a Byte object
Byte b = new Byte("20");
// compareTo method in Byte class
int output = a.compareTo(b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
輸出:
Comparing 20 and 20 : 0
示例2:
// Java code to demonstrate
// Byte compareTo() method
class GFG {
public static void main(String[] args)
{
// creating a Byte object
Byte a = new Byte("20");
// creating a Byte object
Byte b = new Byte("10");
// compareTo method in Byte class
int output = a.compareTo(b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
輸出:
Comparing 20 and 10 : 10
示例3:
// Java code to demonstrate
// Byte compareTo() method
class GFG {
public static void main(String[] args)
{
// creating a Byte object
Byte a = new Byte("10");
// creating a Byte object
Byte b = new Byte("20");
// compareTo method in Byte class
int output = a.compareTo(b);
// printing the output
System.out.println("Comparing " + a
+ " and " + b + " : "
+ output);
}
}
輸出:
Comparing 10 and 20 : -10
