Cyber police wanted to investigate a case; they wanted to check a list of phone numbers that had 945 anywhere in the phone number. Example: 7394567938, 7685483945.., a method was created to convert the phone number in long data type to a string and check for the existence of the number 945. Fill in the blanks (a) and (b) in the given method with appropriate Java statements:

void check(long pno) 
{ String s = _______(a)_________; 
if(______(b)_______) 
    System.out.println(pno); 
}                                    

A manager wants to check the number of employees with names ending with KUMAR, and fill in the blanks in the given program segment with appropriate Java statements:

void count(String s[]) 
{ 
    int i, l=_________, c=0; 
    for(i=0;i<l;i++) 
    { 
    if(________________) 
    c++; 
    } 
    System.out.println(c); 
}                       

Give the output of the following program segment:

for(k=a;k<=a*b;k+=a) 
{ if (k%b==0) 
   break; 
} 
System.out.println(k);

Give the output when a = 6, b = 4.

Kamal wants to display only the alphabets stored in a character array. While compiling the code, an error was displayed. Check for the statement with the error and write the correct statement.
