Analyze the below code and invoke the method using main method. Please help me with this problem.

Question

public int compareTo(String anotherString)
{
int len1 = value.length;
int le2 = anotherString.value.length;
int lim = Math.min(len1, len2);
char v1[] = value;
char v2[] = anotherString.value;

int k = 0;
whlie (k < lim) {
char c1 = v1[k];
char c2 = v2[k];
if (c1 != c2) {
return c1 - c2;
}
k++;
}
return len1 - len2;
}

Answer 1

Prashant Pal This code seems incomplete and wrong because there is no any string with value and what is anotherString.value.length. We get length of string but what is here anotherString.value?

Answer 2

Not getting you all.

Answer 3

No.. i need to invoke this method using main method and generate same output as built-in method compareTo() gives.

Answer 4

whlie was just typing mistake by me.😅

Answer 5

The provided code is exactly the source code of the method compareTo implemented inside the String class: see for example http://hg.openjdk.java.net/jdk7u/jdk7u6/jdk/file/8c2c5d63a17e/src/share/classes/java/lang/String.java at line 1137

A simple example which invokes this method is here:

Prashant Pal Share your complete Code.

Answer 7

I think he has no code at all, just a quiz in some test to explain the use of compareTo method in String class.
By the way there is a typo during the copy of the method: 'whlie' instead of 'while'
