Java Strings Part 2

How many string literals will be created in the constant pool of the code below

public class Strings {
        private static String STATIC="working";
        private String a = null;
public static void main(String ads[]){
String a="working";
                Strings st= new Strings();
                st.a="working";
System.out.println(Strings.STATIC==a);
}
}

 

What will be the output of the following code ? 

public class Strings {
	public static void main(String ads[]){
		String arr[]={"meow","bray","moo"};
		String a="meow";
		System.out.println(arr[0]==a);
	}
}

 

What is the output of the following program ? 


public class Strings {
	public static void main(String ads[]){
		String a="meow";
		String ab=a+"deal";
		String abc="meowdeal";
		System.out.println(ab==abc);
	}
}

 

What will be the output of the following code snippet if tried to compile and run

String x= "abc"
String y= "xyz";
x.concat(y);
System.out.print(x);

 

What happens when you compile and run the program ?  

public class Strings {
	public static void main(String ads[]){
		String abc="abc";
		String bed="bed";
		String comb="abcBED";
		System.out.println(abc+bed.equalsIgnoreCase(comb));
	}
}
