Java Long 클래스의 Compare() 메서드는 두 개의 Long 개체를 수치적으로 비교하는 데 사용됩니다.

통사론:

 public static int compare(long x, long y) 

매개변수:

위의 방법은 두 가지 매개변수로 구성됩니다.

1. 비교해야 할 첫 번째 긴 값입니다.
2. 비교해야 하는 두 번째 긴 값입니다.

반품:

위의 메서드는 다음을 반환합니다.

1. x==y이면 0입니다.
2. x인 경우 0보다 작은 값
3. x>y인 경우 0보다 큰 값입니다.

 public class JavaLongcompareExample1 { public static void main(String[] args) { Long s1 = 76l; Long s2 = 42l; int obj = Long.compare(s1, s2); if(obj==0) { System.out.println('Both the long values are same.'); } else if(obj>0) { System.out.println('The value ''+s1+'' is greater than '+s2); } else { System.out.println('The value ''+s1+'' is smaller than '+s2); } } } 

산출:

 The value '76' is greater than 42
