Java BigDecimal max()用法及代码示例



Java中的java.math.BigDecimal.max(BigDecimal val)方法用于比较两个BigDecimal值,并返回两个最大值。这与Java中的BigDecimal max()方法相反。

用法:

public BigDecimal max(BigDecimal val)

参数:该函数接受BigDecimal对象val作为参数,将其值与此BigDecimal对象的值进行比较,并返回最大值。


返回值:此方法返回BigDecimal,其值大于此BigDecimal和val中的较大者。如果两者相等,则返回此BigDecimal。

例子:

Input :  a = 17.000041900, b = 17.0000418999
Output : 17.000041900

Input : a = 235900000146, b = 236000000000
Output : 236000000000

下面的程序将说明BigDecimal类的max()函数。

示例1:

// Java program to illustrate use of 
// BigDecimal max() function in Java       
import java.math.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // create 2 BigDecimal objects 
        BigDecimal a, b; 
  
        a = new BigDecimal("235900000146"); 
        b = new BigDecimal("236000000000"); 
  
        // print the maximum value 
        System.out.println("Maximum Value among " + a +  
                       " and " + b + " is " + a.max(b)); 
    } 
}
输出:
Maximum Value among 235900000146 and 236000000000 is 236000000000

示例2:

// Java program to illustrate use of BigDecimal max()  
// to display maximum length among two strings in Java   
import java.math.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // Create 2 BigDecimal objects 
        BigDecimal a, b; 
        String s = "GeeksforGeeks"; 
        String str = "GeeksClasses"; 
  
        int l1, l2; 
        l1 = s.length(); 
        l2 = str.length(); 
  
        a = new BigDecimal(l1); 
        b = new BigDecimal(l2); 
  
        // Print the respective lengths 
        System.out.println("Length of string " + s + " is " + a); 
        System.out.println("Length of string " + str + " is " + b); 
          
        // Print the maximum value 
        System.out.println("Maximum length is " + a.max(b)); 
    } 
}
输出:
Length of string GeeksforGeeks is 13
Length of string GeeksClasses is 12
Maximum length is 13
