Java code

 String[] columns = [NAME,CLASS_ID];
        String[] columnsType=[VARCHAR2,INT];
        
        
        sqlEndbBuffer.append("create or replace table "+tableN+"( ");
        
        for(int i=0;i<columns.length;i++){
            
            sqlEndbBuffer.append(columns[i]+" ");
            
            for(int j=0;j<columnsType.length;j++){
                
                sqlEndbBuffer.append(columnsType[j]);
                break；
            }
            break;
            if (i == columnsType.length - 1) {
                sqlEndbBuffer.append("");
            } else {
                sqlEndbBuffer.append(",");
            }
        }
        
        sqlEndbBuffer.append(" )");
        
        System.out.println("New SQL==="+sqlEndbBuffer.toString());

------解决方案--------------------
break 只能跳出最近一个代码循环块

彻底退出 只能用return

所以 楼主可以用一些标志
