ex11.java

JAVA的一些例子,大家可以参考一下

class ex11{
	private int[][] a;
	private int i,j;
	void doubleArray(int i, int j, int low, int upper, int value){
		this.i = i;
		this.j = j;
		a = new int[i][j];
		if(value >= low && value <= upper)
			for(int m = 0; m < i; ++m)
				for(int n = 0; n < j; ++n)
					a[m][n] = value;
	}
	
	void printArray(){
		int m,n;
		for( m = 0; m < i; ++m){
			for( n = 0; n < j; ++n){
				System.out.print(a[m][n] +  " ");
				if( n == (j-1) )System.out.print("\n");
			}//for	
		}//for
		System.out.print("\n");	
			
	}
	
	public static void main(String args[]){
		ex11 e = new ex11();
		e.doubleArray(3, 5, 1, 50, 14);
		e.printArray();
		e.doubleArray(3, 5, 1, 50, 60);//out of
		e.printArray();
	}
