“Dashatize It” in Java

The problem#

Given a variable `n`,

If `n` is an integer, Return a string with sprint`'-'`marks earlier than and after every odd integer, however don’t start or finish the string with a splash mark. If `n` is destructive, then the destructive signal needs to be eliminated.

If `n` just isn’t an integer, return an empty worth.

Ex:

``````dashatize(274) -> '2-7-4'
dashatize(6815) -> '68-1-5'
``````

The answer in Java code#

Possibility 1:

``````public class Resolution {
public static String dashatize(int num) {
String n = String.valueOf(Math.abs(num)).replaceAll("-", "");
return java.util.Arrays.asList(n.break up("")).stream()
.map(ch -> Integer.valueOf(ch) % 2 !=0 ? "-"+ch+"-" : ch)
.acquire(java.util.stream.Collectors.becoming a member of(""))
.replaceAll("--", "-")
.replaceAll("^-+", "")
.replaceAll("-+\$", "");
}
}
``````

Possibility 2:

``````public class Resolution {
public static String dashatize(remaining int quantity) -\$", "");

}
``````

Possibility 3:

``````import java.util.*;
public class Resolution {
public static String dashatize(int num) (?<=[1,3,5,7,9])"));

}
``````

Take a look at circumstances to validate our answer#

``````import org.junit.Take a look at;
import static org.junit.Assert.assertEquals;
import org.junit.runners.JUnit4;

public class SolutionTest {

@Take a look at
public void testBasic() {
assertEquals("2-7-4", Resolution.dashatize(274));
assertEquals("5-3-1-1", Resolution.dashatize(5311));
assertEquals("86-3-20", Resolution.dashatize(86320));
assertEquals("9-7-4-3-02", Resolution.dashatize(974302));
}

@Take a look at
public void testWeird() {
assertEquals("0", Resolution.dashatize(0));
assertEquals("1", Resolution.dashatize(-1));
assertEquals("28-3-6-9", Resolution.dashatize(-28369));
}

@Take a look at
public void testEdgeCases() {
assertEquals("2-1-4-7-48-3-64-7", Resolution.dashatize(Integer.MAX_VALUE));
assertEquals("2-1-4-7-48-3-648", Resolution.dashatize(Integer.MIN_VALUE));
assertEquals("1-1-1-1-1-1-1-1-1-1", Resolution.dashatize(-1111111111));
}
}
