    Code:
    
    
    class Merge{
    	public static void main(String[] args){
    		int[]A = {1,2,};
    		int[]B = {7,8,9};
    		int[]C = new int[A.length + B.length];
    		
    		int aIndex = 0;
    		int aCount = A.length;
    		int cIndex = C.length;
    		
    		
    		while (aIndex < aCount){
    			if(A[aIndex] < B[aIndex]){
    				C[aIndex]= A[aIndex];
    				}
    			aIndex++;
    		
    		}//end while
    		
    		for(int bIndex = 1; bIndex < cIndex ; bIndex++){
    			C[bIndex] = B[bIndex];//Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3
        								//at Merge.main(Merge.java:23)
    	
    		}
    		
    		for (int i = 0; i < C.length; i++){
    			System.out.println(C[i]);
    		}
    		
    	}//end main
    }//end class

    after this code...
    while (aIndex < aCount){
    if(A[aIndex] < B[aIndex]){
    C[aIndex]= A[aIndex];
    }
    aIndex++;

    }//end while
    indexing in array c is 1 size more than size of array
    so u need to first decrease by 1, and then ur program will never shows exception
    try it...
