String Arrays in JAVA


String arrays

Steps:

Step-1: Declare String object and call the methode getNames()

Step-2: Use for loop to print

Step-3: Inside for loop, check if the string is null

Step-4: If string not null, then pring names usring Sysem.out.println(names[i])

         Here after main() will be the method definition for getNames()

Example-1:

package com.example;
public class arrays
{

public static void main(String[] args)

{

String [] names = getNames();
for(int i=0; i<names.length;i++)

{

if (names[i] != null)

{

System.out.println(names[i];

}

}

}

/**
* method to input String array
* Unlike an array where by default all element get initialized to ‘0’
* In an String array by default all the elements are initialized to null
* @return names
*/
public static String[] getNames()
{

String[] names = new String[5];
names[0] = “Abhay”;
names[1] = “Banwari Lal”;
names[2] = “Chanchal”;
names[3] = “devender”;
names[4] = “Ekta”

//the last element of an array will cntain a special value null values; remember in numeric arrays, when we created array they by default cntained 0’s
return names;

}

}

Example-2: To print fist character of every names

package com.example;
public class arrays
{

public static void main(String[] args)
{

String [] names = getNames();
for(int i=0; i<names.length;i++)

{

if (names[i] != null)

{

System.out.println(names[i].charAt(0);

}

}

}

/**
* method to input String array
* Unlike an array where by default all element get initialized to ‘0’
* In an String array by default all the elements are initialized to null
* @return names
*/
public static String[] getNames()
{

String[] names = new String[5];
names[0] = “Abhay”;
names[1] = “Banwari Lal”;
names[2] = “Chanchal”;
names[3] = “devender”;

//the last element of an array will cntain a special value null values; remember in numeric arrays, when we created array they by default cntained 0’s

return names;

}

}
