String-2 > mixString

Given two strings, a and b, create a bigger string made of the first char of a, the first char of b, the second char of a, the second char of b, and so on. Any leftover chars go at the end of the result.


mixString("abc", "xyz") → "axbycz"
mixString("Hi", "There") → "HTihere"
mixString("xxxx", "There") → "xTxhxexre"

Mix String:
dwa stringi o roznej dlugosci
Musimy przejsc loopem przez oba i zlozyc nowy string . aby miec pewnosc ze iterujemy po wszystkich char w stringu wybieramy dluzszy. Konieczne zadeklarowanie zmiennej String str ktora bedzie przechowywala kolejne char



public String mixString(String a, String b){
    
    String str = "";
    int len = 0;

    if (a.length() >= b.length())
    {
        len = a.length();
    } else
        len = b.length();

    for (int i = 0; i < len; i++)
    {

        if (i < a.length())
        {
            str += a.charAt(i);
        }

        if (i < b.length())
        {
            str += b.charAt(i);
        }

    }
    return str;
}

Java - variables , data types

Data Types Data types in Java are classified in to types: Primitive - which include Integer, Character, Boolean and Floating Point Non-primitive - which includes Classes, Interfaces and Arrays Integer : byte 1 byte short 2 bytes int 4 bytes long 8 bytes Floating Point : number + fractional parts  float double Character : stores character Boolean : hold true false value Variables  Instance Variables (non-Static Fields) -  Objects store their individual states in “non-static fields”, that is, fields declared without the static keyword. Class Variables - Static Fields - any field with static modifier says that there is only one copy of this variable in existence static int myClassVariable = 6;  Local Variables - a method stores it's temporary state of local variables int count=0; Parameters - variables which will be passed to the methods of a class
