IntStream distinct()是java.util.stream.IntStream中的方法。此方法返回由不同元素組成的流。這是有狀態的中間操作,即,在處理新元素時,它可以合並先前看到的元素的狀態。
用法:
IntStream distinct() Where, IntStream is a sequence of primitive int-valued elements.
下麵給出一些示例,以更好地理解該函數。
示例1:打印Integer流的不同元素。
// Java code for IntStream distinct()
import java.util.*;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args) {
// creating a stream
IntStream stream = IntStream.of(2, 3, 3, 5, 6, 6, 8);
// Displaying only distinct elements
// using the distinct() method
stream.distinct().forEach(System.out::println);
}
}
輸出:
2 3 5 6 8
示例2:計算流中不同元素的值。
// Java code for IntStream distinct() method
// to count the number of distinct
// elements in given stream
import java.util.*;
import java.util.stream.IntStream;
class GFG {
// Driver code
public static void main(String[] args) {
// creating a stream
IntStream stream = IntStream.of(2, 3, 3, 5, 6, 6, 8);
// storing the count of distinct elements
// in a variable named total
long total = stream.distinct().count();
// displaying the total number of elements
System.out.println(total);
}
}
輸出:
5
