Arrays, References, Memory Leaks

•                      Arrays are references! 

•                      Garbage collection reclaims arrays that can not be accessed! 

•                      References are initialized to null 

•                      When done with a reference set it to null 

public classArrayExamples{public static void main( String args[] )

{int[] integerArray = new int[ 4 ];integerArray[ 1 ] = 12integerArray = new int[ 2 ]; // Memory Leak - No!integerArray[  1  ]  =  5;int[] aliasForArray = integerArray;aliasForArray[  1  ]  =  10;System.out.println( integerArray[ 1 ] ); //Prints 10}

}

HEAP ALLOCATION

integerArray[ 1 ] = 12

integerArray = new int[ 2 ]; // Memory Leak - No!

integerArray[  1  ]  =  5;

int[] aliasForArray = integerArray;

aliasForArray[  1  ]  =  10;

Memory Problems in C/C++

Memory Leaks

Memory that program has allocated but can no longer access  int* trouble = new int( 5 );
