Question
Given1. class Program{2. 3. public static void main(String args[]){4. 5. final String s = "JAVA";6. 7. switch(s){8. case "JAVA" : {System.out.print("A");}9. case "java" : {System.out.print("B");}10. case default : System.out.print("default"); break;11. }12. }13. } Which is the output could be?*Compilation fails due to error at line 10.Compilation fails due to error at line 7.ABdefaultCompilation fails due to error at line 8.A
Solution
The output will be "A". This is because the switch statement checks the value of the variable 's', which is "JAVA". It matches the first case "JAVA" and executes the corresponding code block, which prints "A". The switch statement does not have a break statement after the first case, so it does not exit the switch after executing the first case. However, since none of the other cases match the value of 's', no other code blocks are executed. Therefore, the output is just "A".

Analyze the following code carefully. Please select the one that applies.public class Test { public static void main(String[] args) { A a = new A(); a.print(); }}class A { String s; A(String s) { this.s = s; }void print() { System.out.println(s); }}Group of answer choicesThe program would compile and run if you change A a = new A() to A a = new A(5).The program has a compile error because class A does not have a default constructor.The program compiles and runs fine and prints nothing.The program has a compile error because class A is not a public class.
