Completed Hangman game This works for the most part. I am very new to programming so be aware.

import java.util.*;
public class HangManP5 
{
private static Scanner k;
public static void main(String[] args) 
{
int attempts = 10;
int wordLength;
boolean solved;
k = new Scanner(System.in);

System.out.println("Hey, what's your name?");
String name = k.nextLine();
System.out.println(name+ ", hey! This is a hangman game! (Some answers have two words, usually the longer ones\n");
String word = getRandomWord();
int len = word.length(); 
char[] temp = new char[len];
for(int i = 0; i &lt; temp.length; i++)
{
    temp[i] = '*';
}
System.out.print("\n");
System.out.print("Word to date: "+len+" letters.");
while (attempts &lt;= 10 &amp;&amp; attempts &gt; 0)
{
    System.out.println("\nAttempts left: " + attempts);
    System.out.print("Enter letter: ");
    String test = k.next();
    if(test.length() != 1) 
    {
        System.out.println("Please enter 1 character");
        continue;
    }
    char testChar = test.charAt(0);
    int foundPos = -2;
    int foundCount = 0;
    while((foundPos = word.indexOf(testChar, foundPos + 1)) != -1)
    {
        temp[foundPos] = testChar;
        foundCount++;
        len--;
    }
    if(foundCount == 0)
    {
        System.out.println("Sorry, didn't find any matches for " + test);
    }
    else
    {
        System.out.println("Found " + foundCount + " matches for " + test);
    }
    for(int i = 0; i &lt; temp.length; i++)
    {
        System.out.print(temp[i]);
    }
    System.out.println();
    if(len == 0)
    {
        break; //Solved!
    }
    attempts--;
}
if(len == 0)
{
    System.out.println("\n---------------------------");
    System.out.println("You did iiiiiiit!");
}
else
{
    System.out.println("\n---------------------------");
    System.out.println("Better luck next time, you didn't get the word!");
    System.out.println("It was \"" + word + "\"");
}
}
public static String getRandomWord() 
{
    switch(new Random().nextInt(5)) 
    {
        case 1:
            return "peace";
        case 2:
            return "nuts";
        case 3:
            return "dankmemes";
        case 4:
            return "fizz";
        case 5:
            return "awesome"; 
        default:
            throw new IllegalStateException("Something went wrong!");
    }
}
}
This program is not bad, for a beginner.  You split the getRandomWord() routine into its own function, which is good.  You should do much more of that, though, as your main() is too long to follow at a glance.

The getRandomWord() function has a serious bug arising from your misuse of Random.nextInt(int n).  Possible outputs from that call are 0, 1, 2, 3, 4.  Therefore, it will never choose "awesome", and it may throw an IllegalStateException.  I don't recommend using a switch statement for that purpose, though, because the vocabulary list should be treated as data, not as code.  It would be better to pick a random element from an array of strings.

You also have a logic bug that lets the user "win" by guessing the same correct letter again and again.  For example, if the word is "fizz", and the user guesses 'z', then you record the fact that there are two blanks remaining.  If the user guesses 'z' again, you report a win.  (You really ought to handle duplicate guesses better, but at the least you should prevent such erroneous wins.)

A block of variable declarations at the top of your main() function is unfriendly — nobody likes reading those.  Instead, declare your variables as close to the point of use as possible.  In fact, within your block of declarations are two unused variables wordLength and solved that you yourself lost track of.

Pick variable names that make sense — not just to you but to any programmer who might come along.  Instead of k (short for "keyboard"?), pick input (and initialize it immediately).  Instead of temp (which isn't temporary, so it must mean "template"?), try wordDisplay.

Suggested implementation

This is mostly just a result of


refactoring your main() code into functions
renaming variables for clarity
writing some loops a bit more eloquently
