JAVA ASCII Table

Fork of https://code.google.com/p/java-ascii-table/

ASCII TABLE is a simple framework for generating ASCII tables printable in console and JSPs. It also provides enhanced APIs to get table buffer which can be rendered in Web pages.

Install via gradle:

repositories {
    maven { url 'http://maven.subey.net' }
}

dependencies {
    compile 'com.bethecoder:ascii_table:1.0-SNAPSHOT'
}

Example1

String [] header = { "User Name",
            "Salary", "Designation",
            "Address", "Lucky#"
            };

String[][] data = {
            { "Ram", "2000", "Manager", "#99, Silk board", "1111"  },
            { "Sri", "12000", "Developer", "BTM Layout", "22222" },
            { "Prasad", "42000", "Lead", "#66, Viaya Bank Layout", "333333" },
            { "Anu", "132000", "QA", "#22, Vizag", "4444444" },
            { "Sai", "62000", "Developer", "#3-3, Kakinada"  },
            { "Venkat", "2000", "Manager"   },
            { "Raj", "62000"},
            { "BTC"},
};


ASCIITable.getInstance().printTable(header, data);

It prints the following table in the console.

+-----------+--------+-------------+------------------------+---------+
| User Name | Salary | Designation |         Address        |  Lucky# |
+-----------+--------+-------------+------------------------+---------+
|       Ram |   2000 |     Manager |        #99, Silk board |    1111 |
|       Sri |  12000 |   Developer |             BTM Layout |   22222 |
|    Prasad |  42000 |        Lead | #66, Viaya Bank Layout |  333333 |
|       Anu | 132000 |          QA |             #22, Vizag | 4444444 |
|       Sai |  62000 |   Developer |         #3-3, Kakinada |         |
|    Venkat |   2000 |     Manager |                        |         |
|       Raj |  62000 |             |                        |         |
|       BTC |        |             |                        |         |
+-----------+--------+-------------+------------------------+---------+

Example2

ASCIITableHeader[] headerObjs = {
          new ASCIITableHeader("User Name", ASCIITable.ALIGN_LEFT),
          new ASCIITableHeader("Salary"),
          new ASCIITableHeader("Designation", ASCIITable.ALIGN_CENTER),
          new ASCIITableHeader("Address", ASCIITable.ALIGN_LEFT),
          new ASCIITableHeader("Lucky#", ASCIITable.ALIGN_RIGHT),
};

String[][] data = {
          { "Ram", "2000", "Manager", "#99, Silk board", "1111"  },
          { "Sri", "12000", "Developer", "BTM Layout", "22222" },
          { "Prasad", "42000", "Lead", "#66, Viaya Bank Layout", "333333" },
          { "Anu", "132000", "QA", "#22, Vizag", "4444444" },
          { "Sai", "62000", "Developer", "#3-3, Kakinada"  },
          { "Venkat", "2000", "Manager"   },
          { "Raj", "62000"},
          { "BTC"},
};


ASCIITable.getInstance().printTable(headerObjs, data);

It prints the following table in the console.

+-----------+--------+-------------+------------------------+---------+

            "Salary", "Designation",
            "Address", "Lucky#"
            };

Example4

The following example shows rendering the ASCII Table from database. It uses H2 database for getting BUG_STAT, USER table contents.

//Need to have h2-1.3.160.jar in classpath.
Class.forName("org.h2.Driver");
Connection conn = DriverManager.getConnection(
      "jdbc:h2:tcp://localhost/~/test", "sa", "");

//Print BUG_STAT table
IASCIITableAware asciiTableAware = new JDBCASCIITableAware(
                      conn, "select STATUS, COUNT from BUG_STAT");
ASCIITable.getInstance().printTable(asciiTableAware);

//Print USER table
asciiTableAware = new JDBCASCIITableAware(
                      conn, "select * from USER");
ASCIITable.getInstance().printTable(asciiTableAware);

It prints the following tables in the console.

+----------+-------+
|  STATUS  | COUNT |
+----------+-------+
|      NEW |     8 |
| ASSIGNED |    12 |
| RESOLVED |    16 |
|   REOPEN |     2 |
| VERIFIED |    16 |
|   CLOSED |     6 |
+----------+-------+

+----+----------+-----+------------+
| ID |   NAME   | AGE |   SALARY   |
+----+----------+-----+------------+
|  1 |   Sriram |   2 | 20,000,000 |
|  2 |      Anu |  28 |  4,800,000 |
|  3 | Sudhakar |  29 | 19,800,000 |
|  4 |   Charan |   3 | 10,000,000 |
|  5 |    Bunny |   2 | 16,000,000 |
+----+----------+-----+------------+

Example5

The following example shows rendering the ASCII Table from list of java beans.

Employee stud = new Employee("Sriram", 2, "Chess", false, 987654321.21d);
Employee stud2 = new Employee("Sudhakar", 29, "Painting", true, 123456789.12d);
List<Employee> students = Arrays.asList(stud, stud2);

IASCIITableAware asciiTableAware =
        new CollectionASCIITableAware<Employee>(students,
                        //properties to read
                        "name", "age", "married", "hobby", "salary");
ASCIITable.getInstance().printTable(asciiTableAware);


asciiTableAware =
        new CollectionASCIITableAware<Employee>(students,
        //properties to read
        Arrays.asList("name", "age", "married", "hobby", "salary"),
        Arrays.asList("STUDENT_NAME", "HIS_AGE")); //custom headers

ASCIITable.getInstance().printTable(asciiTableAware);

It prints the following tables in the console.

+----------+-----+---------+----------+----------------+
|   NAME   | AGE | MARRIED |   HOBBY  |     SALARY     |
+----------+-----+---------+----------+----------------+
|   Sriram |   2 |   false |    Chess | 987,654,321.21 |
