How to used 2 different method to populate and show String array content

[betny]

private String [][] personalDetails() {

        logger.debug( "personalDetails()" );

        String personArray [][] =
            {
              { "John",  " Muray", "1-10-1982" },
              { "Peter",  " Kamau", "2-5-1987" },
              { "Mary",  " Wambui", "8-5-1988" },
              { "Bethu",  " Kips", "8-8-1987" },
              { "Cetera",  " Omosh", "2-5-1987" }

            };   
           
          return personArray;

       
    }
  
       /**
     * Demonstrates initializing and populating a multi-dimensional array
     * in one statement
     */
   private void personalDetailsContent( ) {

        logger.debug( "personalDetailsContent()" );
            
             String [][] personArray= new String[ 5 ][5];
              for(int i=0; i<=personArray.length; i++){
                  for(int j=0; j<=personArray[i].length; j++){
                   personArray[i][j]=i;
                  }
                System.out.println( "Names " + i +  "" + j +" : " + personArray[ i ][j] );
              }

Do you have a question?

Please create a multi dimensional array that stores the following
information for 5 people:

* First Name
* Last Name
* Date of Birth
Your application should have one method that populates the multi
dimensional array with data and another method that shows the contents
of the multi dimensional array.
Have gone this far:

private String [][] personalDetails() {

logger.debug( "personalDetails()" );

String personArray [][] =
{
{ "John", " Muray", "1-10-1982" },
{ "Peter", " Kamau", "2-5-1987" },
{ "Mary", " Wambui", "8-5-1988" },
{ "Bethu", " Kips", "8-8-1987" },
{ "Cetera", " Omosh", "2-5-1987" }

};

return personArray;

}

/**
* Demonstrates Showing the content a multi-dimensional array
* in a different method from populating method.
*/
private void personalDetailsContent( ) {

logger.debug( "personalDetailsContent()" );

String [][] personArray= new String[ 5 ][5];

for(int i=0; i<=personArray.length; i++){

for(int j=0; j<=personArray[i].length; j++){
System.out.println( "Person index " + j +" : " + personArray[i][j] );

}

}
}

Error: Exception in thread 'main' java.lang.IndexOutOfBoundException: 5

Arrays are 0 based,, so a [5] array has length 5 and indexes 0-4
Your loop
for(int i=0; i<=personArray.length; i++){
will attempt to access indexes 0-5, and will fail on the last one with an IndexOutOfBounds (5)
