Java 中的 LongAdder toString()方法，带示例
原文:https://www . geesforgeks . org/long adder-tostring-method-in-Java-with-examples/
Java 中的 LongAdder 类创建一个初始和为零的新加法器。爪哇。LongAdder.toString() 是 Java 中的一个内置方法，返回这个 LongAdder 的 String 表示。创建类的对象时，其初始值为零。
语法:
public String toString()
参数:函数不接受任何参数。
返回值:该方法返回一个字符串值，它是这个长加法器的字符串表示。
以下程序演示了上述功能:
程序 1:
// Java program to demonstrate
// the LongAdder.toString() method
import java.lang.*;
import java.util.concurrent.atomic.LongAdder;
public class GFG {
public static void main(String args[])
{
// Initialized with 0
LongAdder num = new LongAdder();
// Print the initial value
System.out.println("Initial value is: "
+ num);
// Add 6 to it
num.add(6);
// Print the final value
System.out.println("After addition"
+ " of 6, value is: "
+ num);
// Add 5 to it
num.add(5);
// Print the final value
System.out.println("After addition"
+ " of 5, value is: "
+ num);
// toString operation on num
System.out.println("String representation"
+ " of the LongAdder: "
+ num.toString());
}
}
Output:
Initial value is: 0
After addition of 6, value is: 6
After addition of 5, value is: 11
String representation of the LongAdder: 11
程序 2:
// Java program to demonstrate
// the LongAdder.toString() method
import java.lang.*;
import java.util.concurrent.atomic.LongAdder;
public class GFG {
public static void main(String args[])
{
// Initialized with 0
LongAdder num = new LongAdder();
// Print the initial value
System.out.println("Initial value is: "
+ num);
// Add 10 to it
num.add(10);
// Print the final value
System.out.println("After addition"
+ " of 10, value is: "
+ num);
// Add 100 to it
num.add(100);
// Print the final value
System.out.println("After addition"
+ " of 100, value is: "
+ num);
// toString operation on num
System.out.println("String representation"
+ " of the LongAdder: "
+ num.toString());
}
}
Output:
Initial value is: 0
After addition of 10, value is: 10
After addition of 100, value is: 110
String representation of the LongAdder: 110
