the first long to compare y Int64 the second long to compare Returns Int32 the value 0 if x == y; a value less than 0 if x < y; and a value greater than 0 if x > y Attributes RegisterAttribute Remarks Java documentation for java.lang.Long.compare(long, long). Portions of ...
Here, four long values n1, n2, n3, n4 are taken in an array and are checked for the values are either less, more, or equal when compared with the first value of the array. import java.lang.Long; public class StudyTonight { public static void main(String[] args) { long []n = {...
它返回 0,如果value1在数学上等于value2。 它返回值 < 0,如果value1在数学上小于value2。 它返回值 > 0,如果value1在数学上大于value2。 例: // Java program to demonstrate the example// ofcompareTo(Long value2) method of Long classpublicclassCompareToOfLongClass{publicstaticvoidmain(String[] arg...
} The output: equals(Object obj)compares this object to the specified object. The result istrueif and only if the argument is not null and is aByteobject that contains the same byte value as this object. publicclassMain {publicstaticvoidmain(String[] args) {/*fromjava2s.com*/Byte byte...

AtomicLong compareAndSet() method in Java with examples Java.util.concurrent.atomic.AtomicLong.compareAndSet() 是 java 中的一个内置方法,如果当前值等于也传递给范围。该函数返回一个布尔值,它让我们知道更新是否完成。 语法: publicfinalbooleancompareAndSet(longexpect, ...
