How to Create a 2D Boolean Array in Java from Table Data?

How can I create a 2D boolean array in Java based on table data?

String[][] tableData = {{"true", "false"}, {"false", "true"}}; 
boolean[][] booleanArray = new boolean[tableData.length][tableData[0].length]; 

for (int i = 0; i < tableData.length; i++) {
    for (int j = 0; j < tableData[i].length; j++) {
        booleanArray[i][j] = Boolean.parseBoolean(tableData[i][j]);
    }
}

Creating a 2D Boolean array in Java from table data is a straightforward process that involves parsing the data and converting it into a boolean type. This approach is useful when handling datasets where true/false values are represented as strings, such as in CSV files or user input tables.

String[][] tableData = {{"true", "false"}, {"false", "true"}}; 
boolean[][] booleanArray = new boolean[tableData.length][tableData[0].length]; 

for (int i = 0; i < tableData.length; i++) {
    for (int j = 0; j < tableData[i].length; j++) {
        booleanArray[i][j] = Boolean.parseBoolean(tableData[i][j]);
    }
}

Causes

• The data in the table consists of string representations of boolean values ("true" or "false").
• Confusion in the parsing logic can lead to incorrect boolean values in the resulting array.

Solutions

• 1. Initialize a 2D String array with the table data.
• 2. Create a 2D boolean array of the same dimensions.
• 3. Use nested loops to parse each string and convert it to a boolean using Boolean.parseBoolean().
• 4. Ensure proper checking of null or unexpected values to avoid parsing errors.

Mistake: Assuming the string values are always valid boolean representations.

Solution: Implement error handling to check for invalid inputs.

Mistake: Not matching the dimensions of the 2D boolean array with the input data.

Solution: Always initialize the boolean array based on the dimensions of the input data.
