Hi friend,


Code to solve the problem :

public class LinearSearch
{


// Search "array" for the specified "key" value
public static boolean linearSearch( String array[][], int key1,int key2,String strMatch)
{
for ( int n = 0; n <array.length; n++ )
{
for(int m=0;m<array[n].length;m++)
{
if((key1==n) && (key2==m))
{
String str = array[n][m].substring(0,2);
if(str.equals(strMatch))
{
return true;
}
}
}
}

return false;
}


public static void main(String args[])
{

String Data[][] = new String[2][3];

Data[0][0] = "Hello"; //lastname
Data[0][1] = "World"; //firstname
Data[0][2] = "Roseindia"; //location

//Second row
Data[1][0] = "Xyz"; //lastname
Data[1][1] = "Abc"; //firstname
Data[1][2] = "India"; //location


int key1 = 1;
int key2 = 1;
String strmatch = "Ab";

if(linearSearch(Data,key1,key2,strmatch))
{
System.out.println("Item exists");
}
else
{
System.out.println("Item doesn't exists");
}

}
}
