Can somebody help in converting this Python code to Java? class File: def __init__(self, nm, size): self.name = nm self.size = size def __str__(self): return "[ " + self.name + " " + str(self.size) + "GB ]" def __repr__(self): return self.__str__() class Critera: def meetCondition(self, files): pass class NameCritera(Critera): def __init__(self, extension): self.extension = extension def meetCondition(self, files): return list(filter(lambda x: self.extension in x.name, files)) #This xml can be customized as well rather than hardcoding it. class SizeCritera(Critera): def __init__(self, size): self.size = size def meetCondition(self, files): return list(filter(lambda x: x.size > self.size, files)) class AndCriteria: def __init__(self, cr1, cr2): self.cr1 = cr1 self.cr2 = cr2 def apply(self, files): intermediate_output = self.cr1.meetCondition(files) return self.cr2.meetCondition(intermediate_output) class OrCriteria: def __init__(self, cr1, cr2): self.cr1 = cr1 self.cr2 = cr2 def apply(self, files): output1 = self.cr1.meetCondition(files) output2 = self.cr2.meetCondition(files) for _o in output2: if _o not in output1: output1.append(_o) return output1 f1 = File("abc.txt", 10) f2 = File("lmn.xml", 5) f3 = File("pqr.xml", 15) f4 = File("xyz.png", 20) sizeCR1 = SizeCritera(5) sizeCR2 = SizeCritera(15) nameCR1 = NameCritera("xml") nameCR2 = NameCritera("txt") a1 = AndCriteria(sizeCR1, nameCR1) o1 = OrCriteria(sizeCR2, nameCR2) print(a1.apply([f1, f2, f3, f4])) print(o1.apply([f1, f2, f3, f4]))
