Question

1. Write a Java statement to compare the string in s1 to the string in s2 for equality of content.
2. What a Java statement to determine the length of the string in s1.
3. Write a Java statement to split the string in s1 into tokens, using " " as the delimiter, and stored the results in a variable named tokens.

Answer 1

Answer(1): Compare content of strings-

String S1 = "Hello";
String S2 = "Hello";
System.out.println(S1.equals(S2));  //compare the contents of strings S1 and S2.

Output : true

Answer(2): length of a string-

String S1 = "This is a string";
System.out.println(Str1.length()); //this will print the length of string S1,that is: 16

Output : 16

Answer(3): tokenize the string by delimiter " " -

String S1 = "This is a string";
String[] tokens = S1.split(" ");  //array of strings
for (String token : tokens)
{
    System.out.println(token);   //this will print all tokens one by one 
}

Output : This

is

a

string

Hope this helps!
