String s1 = "45.50"; String s2 = "54.50";
double d1=Double.parseDouble(s1);
double d2=Double.parseDouble(s2);
int x= (int)(d1+d2);

What is value of x?

Predict the output of the following code snippet:

char ch='B',
char chr=Character.toLowerCase(ch); 
int n=(int)chr-10; 
System.out.println((char)n+"\t"+chr);

State the data type and value of res after the following is executed:

char ch = '9';
res= Character.isDigit(ch);
