JAVA小练习85——String类常用构造方法

public class Demo85 {
	
	public static void main(String[] args) {
		String str = new String();//创建了一个 空字符串对象。
		System.out.println("字符串："+ str);
		
		
		byte[] buf = {97,98,99};
		str = new String(buf);
		str = new String(buf,1,2);
		System.out.println("字符串："+ str);
		
		
		char[] arr= {'传','智','播','客'};
		str = new String(arr);
		str = new String(arr,0,2);
		System.out.println("字符串："+ str);
		
		
		str = new String("字符串");
		System.out.println("字符串："+ str);
		
		
		
	}
