a. The error in this code is that you are trying to assign an array to an array element. You should initialize array2 before assigning values to it. Corrected code:

```java
int[] array1={5,10,15};
int[] array2 = new int[3];
array2[0] = array1[0];
```

b. The error in this code is that you are using a variable 'ar' which is not declared. Also, the loop will throw an ArrayIndexOutOfBoundsException because the size of the array 'letters' is 5 and you are trying to access up to the 10th index. Corrected code:

```java
char[] letters=new char[10];
int x = 0;
while(x

a. The error in this code is that you are trying to assign an array to an array element. You should initialize array2 before assigning values to it. Corrected code:

```java
char[] letters=new char[10];
int x = 0;
while(x < 10){
    letters[x]='a';
    x++;
}
```

c. The error in this code is that you are trying to use a method length() on an array. Arrays in Java have a property 'length' not a method. Also, you forgot to add '()' after 'names[i].length'. Corrected code:

```java
String[] names = { "George", "Susan" };
int totalLength = 0;
for (int i = 0; i < names.length; i++)
    totalLength += names[i].length();
```

d. The error in this code is that you are trying to access the 3rd index of the array 'names' which is out of bounds. In Java, array indices start from 0. So, for an array of size 3, valid indices are 0, 1, and 2. Corrected code:

```java
String[] names = new String[3];
names[0] = "Bill";
names[1] = "Susan";
names[2] = "Bob";
```
