コード 

public class Int_class {

	public static void main(String[] args) {

		System.out.println("Start");

		//
		System.out.println("------------------------");
		
		System.out.println("Integer.MAX_VALUE -> " + Integer.MAX_VALUE);
		System.out.println("Integer.MIN_VALUE -> " + Integer.MIN_VALUE);
		

		//
		System.out.println("------------------------");

		String sBuff = "125";
		
		Integer intObj = Integer.valueOf(sBuff);
		
		int nBuff1 = intObj.intValue();
		
		nBuff1 += 1;	

		System.out.println("nBuff1 -> " + nBuff1);
		
		
		//
		System.out.println("------------------------");
		
		int nBuff2 = Integer.valueOf(sBuff).intValue();
		
		nBuff2 += 10;
		
		System.out.println("nBuff2 -> " + nBuff2);
		

		//
		System.out.println("------------------------");
		
		System.out.println("End");
		
	}
}


結果 

Start
------------------------
Integer.MAX_VALUE -> 2147483647
Integer.MIN_VALUE -> -2147483648
------------------------
nBuff1 -> 126
------------------------
nBuff2 -> 135
------------------------
