原文:https://www . geesforgeks . org/atomiclong-get-method-in-Java-with-examples/
Java . util . concurrent . atomic . atomic clong . get()是 Java 中的一个内置方法，它返回日期类型长的当前值。
语法:
public final long get()
参数:函数不接受任何参数。
返回值:函数返回当前值
下面的程序说明了上述方法:
程序 1:
// Java program that demonstrates
// the get() function
import java.util.concurrent.atomic.AtomicLong;
public class GFG {
public static void main(String args[])
{
// Initially value as 0
AtomicLong val = new AtomicLong(0);
val.addAndGet(7);
// Prints the updated value
System.out.println("Previous value: "
+ val);
// Gets the current value
long res = val.get();
System.out.println("current value: "
+ res);
}
}
输出:
Previous value: 7
current value: 7
程序二:
// Java program that demonstrates
// the get() function
import java.util.concurrent.atomic.AtomicLong;
public class GFG {
public static void main(String args[])
{
// Initially value as 18
AtomicLong val = new AtomicLong(18);
val.addAndGet(7);
// Prints the updated value
System.out.println("Previous value: "
+ val);
// Gets the current value
long res = val.get();
System.out.println("current value: "
+ res);
}
}
输出:
Previous value: 25
current value: 25
