How to optymalize iteration by list and calling method
问题
I would like to optimize my process of iteration by using a list and filtering it.
For example:
I have a short list of similar objects where the difference will be one field:
List<ObjTest> objects = getListOfObjects();
Next, I would like to check if the list is not empty and iterate through each object, compare fields with input, and if the fields match, I would like to call methodA. Otherwise, when the fields of objects do not match, I would like to call methodB.
Something like:
for (ObjTest objTest : objects) {
if (objTest.getField().equals(input.getField())) {
return methodA(input);
}
}
return methodB(input)
Is it possible to do this with objects.stream?

得分: 1
你可以使用 anyMatch()：
if (objects.stream().anyMatch(o -> o.getField().equals(input.getField()))) {
return methodA(input);
} else {
return methodB(input);
}
英文:
You can use anyMatch():
if (objects.stream().anyMatch(o -> o.getField().equals(input.getField()))) {
return methodA(input);
} else {
return methodB(input);
}
