java - ジャバエラー！他の場所で解決策を見たことがない

Question

私は、1 人の小売業者と複数の購入者による購入のクレジットとデビットを許可するプログラムを作成しています。各買い手が pmnt を購入または作成した後、毎月の要約で各トランザクションが必要です。
これが私が持っているものです。この時点で私が持っている唯一のエラーは次のとおりです。

Main.java:136: error: not a statement
                  displayprocestran;   
                  ^
Main.java:144: error: not a statement
                displayprostrans;
                ^

これはプログラムです：
