IntStream allMatch() method in Java
The allMatch() method of the IntStream class in Java returns whether all elements of this stream match the provided predicate.
The syntax is as follows
boolean allMatch(IntPredicate predicate)
Here, the predicate parameter is a stateless predicate to apply to elements of this stream. The IntPredicate represents a predicate of one int-valued argument.
The allMatch() method returns true if either all elements of the stream match the provided predicate or the stream is empty.
The following is an example to implement IntStream allMatch() method in Java
Example
import java.util.*;
import java.util.stream.IntStream;
public class Demo {
public static void main(String[] args) {
IntStream intStream = IntStream.of(55, 65, 70, 90, 100);
boolean res = intStream.allMatch(a -> a > 50);
System.out.println("Does all the elements of the stream matches the predicate?"+res);
}
}Output
Does all the elements of the stream matches the predicate?true
Example
import java.util.*;
import java.util.stream.IntStream;
public class Demo {
public static void main(String[] args) {
IntStream intStream = IntStream.of(15, 20, 25, 40, 50, 80);
boolean res = intStream.allMatch(a -> a < 30);
System.out.println("Do all the elements of the stream match the predicate? "+res);
}
}Output
Do all the elements of the stream match the predicate? False
