如何将return语句变量传递给另一个函数变量？

Question

在课堂顺序中，它会返回新的BigInteger。我想将新的BigInteger传递给pass_order（）函数变量trx_id。我该怎么做？

public class order {
public final class SessionIdentifierGenerator {
    private SecureRandom random = new SecureRandom();

    public String nextSessionId() {
        return new BigInteger(130, random).toString(32);
    }
}
private void pass_order() {
    String trx_id = SessionIdentifierGenerator(BigInteger;
}

你可以试试这个：）

public class order {
        public final class SessionIdentifierGenerator {
            private SecureRandom random = new SecureRandom();

            public String nextSessionId() {
                return new BigInteger(130, random).toString(32);
            }
        }
        private void pass_order() {
            SessionIdentifierGenerator sessionIDGenerator = new SessionIdentifierGenerator();
            String trx_id = sessionIDGenerator.nextSessionId();
        }
    }
