Question

Explain the statement                         ABC obj=new ABC(); 

d. System.out.println(“PROCESS”.startsWith(“pRO”)); 

System.out.println(Math.sqrt((int)“Quiz”.charAt(0))); 

​

Answer 1

Answer:-

Given statement.

ABC obj=new ABC();

The following statement creates object named obj of ABC class.

Second statement,

System.out.println(“PROCESS”.startsWith(“pRO”)); 

It checks whether the string "PROCESS" starts with "pRO" or not. Here the string starts with PRO but not pRO(both are same but of different case) , so it returns false.

Output:- false.

Third statement.

System.out.println(Math.sqrt((int)“Quiz”.charAt(0)));

"Quiz".charAt(0) extracts the character at first index from the string "Quiz" which is 'Q'.

ASCII value of Q is 81.

81 is converted to integer here.

Math.sqrt(81) calculates the square root of 81 which is equal to 9.0

Output:- 9.0
