Java is well-known for its ability to run on any device or platform thanks to the "Write Once, Run Anywhere" (WORA) philosophy. This is made possible because Java code is compiled into bytecode that runs on the Java Virtual Machine (JVM) instead of being compiled directly into machine code specific to any system.      How Java achieves portability:

    def search(self, k):
        bucket = self.table[hash_fn(k)]

It involves creating a plan to consolidate multiple debts into one manageable monthly payment, often with reduced interest rates or fees.
