The set of characters from U+0000 to U+FFFF is sometimes referred to as the Basic Multilingual Plane (BMP). Characters whose code points are greater than U+FFFF are called supplementary characters. The Java platform uses the UTF-16 representation in char arrays and in the String and StringBu...
The numerical array values are initialized using aforloop; a variablen, which increments from 0 to 9, is used as loop counter and also as the array index value. The character array values are assigned using the functionstrcpy()(string copy). Its arguments are the target array nameastringan...
Let's consider another array with integer values. Input array: [1, 2, 3, 10, 20] Output: 1P2P3P10P20 Here the array elements 1, 2, 3, 10, 20 are joined with the character P. We will use an inbuilt string join() method to join array elements with a specifie...
