java将整数转换为字符串

• 1.toString 适用于int类型

public class test {

	public static void main(String[] args) {
		int i = 777;
		String str = Integer.toString(i);
		System.out.println(str);
	}

}

• 2.valueOf  适用于int、double、boolean和Object类型

public class test {

	public static void main(String[] args) {
		int i = 777;
        String str = String.valueOf(i);
		System.out.println(str);
	}

}

• 3.使用+，java内自动将数字转化成字符串

public class test {

	public static void main(String[] args) {
		int i = 36;
		String str = i + "";
		System.out.println(str);
	}

}

• 4. format

public class test {

	public static void main(String[] args) {
		int i = 36;
		String str = String.format("%d",i);
		System.out.println(str);
	}

}
